Struct freya::elements::rect

pub struct rect;

rect is a generic element that acts as a container for other elements.

You can specify things like width, padding or even in what direction the inner elements are stacked.

Example

fn app() -> Element {
    rsx!(
        rect {
            direction: "vertical",
            label { "Hi!" }
            label { "Hi again!"}
        }
    )
}

Implementations

impl rect

pub const padding: (&'static str, Option<&'static str>, bool) = _

Specify the inner paddings of an element. You can do so by four different ways, just like in CSS.

Example

fn app() -> Element {
    rsx!(
        rect {
            padding: "25", // 25 in all sides
            padding: "100 50", // 100 in top and bottom, and 50 in left and right
            padding: "2 15 25", // 2 in top, 15 in left and right, and 25 in bottom
            padding: "5 7 3 9" // 5 in top, 7 in right, 3 in bottom and 9 in left
        }
    )
}

pub const height: (&'static str, Option<&'static str>, bool) = _

Specify the width and height for the given element.

See syntax in Size Units.

Example

fn app() -> Element {
    rsx!(
        rect {
            background: "red",
            width: "15",
            height: "50",
        }
    )
}

pub const width: (&'static str, Option<&'static str>, bool) = _

pub const min_height: (&'static str, Option<&'static str>, bool) = _

min_width & min_height

rect supports specifying a minimum width and height, this can be useful if you use it alongside a percentage for the target size.

See syntax for Size Units.

Usage

fn app() -> Element {
    rsx!(
        rect {
            background: "red",
            min_width: "100",
            min_height: "100",
            width: "50%",
            height: "50%",
        }
    )
}

pub const min_width: (&'static str, Option<&'static str>, bool) = _

pub const max_height: (&'static str, Option<&'static str>, bool) = _

max_width & max_height

rect supports specifying a maximum width and height.

See syntax for Size Units.

Usage

fn app() -> Element {
    rsx!(
        rect {
            background: "red",
            max_width: "50%",
            max_height: "50%",
            width: "500",
            height: "500",
        }
    )
}

pub const max_width: (&'static str, Option<&'static str>, bool) = _

pub const background: (&'static str, Option<&'static str>, bool) = _

Specify a color as the background of an element.

You can learn about the syntax of this attribute in Color Syntax.

Example

fn app() -> Element {
    rsx!(
        rect {
            background: "red"
        }
    )
}

pub const border: (&'static str, Option<&'static str>, bool) = _

border

You can add borders to an element using the border attribute.

• border syntax: [width] [width?] [width?] [width?] <inner | outer | center> [fill].

1-4 width values should be provided with the border attribute. Widths will be applied to different sides of a rect depending on the number of values provided:

• One value: all
• Two values: vertical, horizontal
• Three values: top horizontal bottom
• Four values: top right bottom left

Border alignment determines how the border is positioned relative to the element’s edge. Alignment can be inner, outer, or center.

Examples

A solid, black border with a width of 2 pixels on every side. Border is aligned to the inside of the rect’s edge.

fn app() -> Element {
    rsx!(
        rect {
            border: "2 inner black",
        }
    )
}

A solid, red border with different widths on each side. Border is aligned to the center of the rect’s edge.

fn app() -> Element {
    rsx!(
        rect {
            border: "1 2 3 4 center red",
        }
    )
}

Borders can take any valid fill type, including gradients.

fn app() -> Element {
    rsx!(
        rect {
            border: "1 inner linear-gradient(red, green, yellow 40%, blue)",
        }
    )
}

Similarly to the shadow attribute, multiple borders can be drawn on a single element when separated by a comma. Borders specified later in the list are drawn on top of previous ones.

fn app() -> Element {
    rsx!(
        rect {
            border: "6 outer red, 5 outer orange, 4 outer yellow, 3 outer green, 2 outer blue, 1 outer purple",
        }
    )
}

pub const direction: (&'static str, Option<&'static str>, bool) = _

Control how the inner elements stack.

Accepted values:

• vertical (default)
• horizontal

Usage

fn app() -> Element {
    rsx!(
        rect {
            width: "100%",
            height: "100%",
            direction: "vertical",
            rect {
                width: "100%",
                height: "50%",
                background: "red"
            },
            rect {
                width: "100%",
                height: "50%",
                background: "green"
            }
        }
    )
}

pub const shadow: (&'static str, Option<&'static str>, bool) = _

Draw a shadow of the element.

Syntax: <x> <y> <intensity> <size> <color>

Example

fn app() -> Element {
    rsx!(
        rect {
            shadow: "0 0 25 2 rgb(0, 0, 0, 120)"
        }
    )
}

pub const corner_radius: (&'static str, Option<&'static str>, bool) = _

corner_radius & corner_smoothing

The corner_radius attribute lets you smooth the corners of the element, with corner_smoothing you can give a “squircle” effect.

Example

fn app() -> Element {
    rsx!(
        rect {
            corner_radius: "10",
            corner_smoothing: "75%"
        }
    )
}

pub const corner_smoothing: (&'static str, Option<&'static str>, bool) = _

pub const color: (&'static str, Option<&'static str>, bool) = _

The color attribute lets you specify the color of the text.

You can learn about the syntax of this attribute in Color Syntax.

Example

fn app() -> Element {
    rsx!(
        label {
            color: "green",
            "Hello, World!"
        }
    )
}

Another example showing inheritance:

fn app() -> Element {
    rsx!(
        rect {
            color: "blue",
            label {
                "Hello, World!"
            }
        }
    )
}

pub const font_size: (&'static str, Option<&'static str>, bool) = _

You can specify the size of the text using font_size.

Example

fn app() -> Element {
    rsx!(
        label {
            font_size: "50",
            "Hellooooo!"
        }
    )
}

pub const font_family: (&'static str, Option<&'static str>, bool) = _

With the font_family you can specify what font you want to use for the inner text.

Check out the custom font example to see how you can load your own fonts.

Example

fn app() -> Element {
    rsx!(
        label {
            font_family: "Inter",
            "Hello, World!"
        }
    )
}

pub const font_style: (&'static str, Option<&'static str>, bool) = _

You can choose a style for a text using the font_style attribute.

Accepted values:

            font_style: "italic",
            "Hello, italic World!"
        }
    )
}

You can also specify multiple fonts in order of priority, if one is not found it will fallback to the next one.

Example:

fn app() -> Element {
    rsx!(
        label {
            font_family: "DoesntExist Font, Impact",
            "Hello, World!"
        }

        }
    )
}

pub const font_width: (&'static str, Option<&'static str>, bool) = _

• extra-expanded
• ultra-expanded

Example

fn app() -> Element {
    rsx!(
        label {
            font_width: "ultra-expanded",
            "Hello, wide World!"
        }
    )
}

pub const main_align: (&'static str, Option<&'static str>, bool) = _

main_align & cross_align

Control how the inner elements are positioned inside the element. You can combine it with the direction attribute to create complex flows.

Accepted values for main_align:

• start (default): At the begining of the axis
• center: At the center of the axis
• end: At the end of the axis
• space-between(only for main_align): Distributed among the available space
• space-around (only for main_align): Distributed among the available space with small margins in the sides
• space-evenly (only for main_align): Distributed among the available space with the same size of margins in the sides and in between the elements.

Accepted values for cross_align:

• start (default): At the begining of the axis (same as in main_align)
• center: At the center of the axis (same as in main_align)
• end: At the end of the axis (same as in main_align)

When using the vertical direction, main_align will be the Y axis and cross_align will be the X axis. But when using the horizontal direction, the main_align will be the X axis and the cross_align will be the Y axis.

Example on how to center the inner elements in both axis:

fn app() -> Element {
    rsx!(
        rect {
            width: "100%",
            height: "100%",
            main_align: "center",
            cross_align: "center",
            rect {
                width: "50%",
                height: "50%",
                background: "red"

            }
        }
    )
}

pub const margin: (&'static str, Option<&'static str>, bool) = _

Specify the margin of an element. You can do so by four different ways, just like in CSS.

Example

fn app() -> Element {
    rsx!(
        rect {
            margin: "25", // 25 in all sides
            margin: "100 50", // 100 in top and bottom, and 50 in left and right
            margin: "2 15 25", // 2 in top, 15 in left and right, and 25 in bottom

        }
    )
}

pub const position: (&'static str, Option<&'static str>, bool) = _

Specify how you want the element to be positioned inside it’s parent area.

Accepted values:

• stacked (default)
• absolute

When using the absolute mode, you can also combine it with the following attributes:

• position_top
• position_right
• position_bottom
• position_left

These only support pixels.

Example

fn app() -> Element {
    rsx!(
        rect {
            width: "100%",
            height: "100%",
            rect {
                position: "absolute",
                position_bottom: "15",
                position_right: "15",

            }
        }
    )
}

pub const content: (&'static str, Option<&'static str>, bool) = _

Specify how you want the automatic (e.g width: auto) bounds in the cross axis to be constrained for the inner elements.

Accepted values:

• normal (default): Uses parent bounds.
• fit: Uses parent bounds but later shrunks to the size of the biggest element inside.

The fit mode will allow the inner elements using width: fill-min to expand to the biggest element inside this element.

Example

fn app() -> Element {
    rsx!(
        rect {
            content: "fit",
            height: "100%",
            rect {
                width: "fill-min", // Will have a width of 300px
                height: "25%",
                background: "red",
            }
            rect {
                width: "150",  // Will have a width of 150px
                height: "25%",

                height: "25%",
                background: "blue",
            }
            rect {
                width: "300",  // Biggest element, will have a width of 300px
                height: "25%",
                background: "black",
            }
        }
    )
}

pub const line_height: (&'static str, Option<&'static str>, bool) = _

                background: "red",
            }
            // There will be a space between these two elements of 20 pixels
            rect {
                width: "100",
                height: "100",
                background: "blue",
            }
