Struct freya::elements::rect

pub struct rect;

Expand description

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 here.

Example

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

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

border & border_align

You can add a border to an element using the border and border_align attributes.

border syntax: [width] <solid | none> [color].
border_align syntax: <inner | outer | center>.

Example

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

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

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!(

            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) = _

        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 {

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!(

            color: "green",
            "Hello, World!"
        }
    )
}

Another example showing inheritance:

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

        }
    )
}

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

You can specify the size of the text using font_size.

            "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!"

            font_weight: "bold",
            "Hello, bold World!"
        }
    )
}

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

    )
}

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 both attributes are:

start (default): At the begining of the axis
center: At the center of the axis
end: At the end of the axis

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 cross_align: (&'static str, Option<&'static str>, bool) = _

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