pub struct UiRect {
pub left: Val,
pub right: Val,
pub top: Val,
pub bottom: Val,
}
Expand description
A type which is commonly used to define margins, paddings and borders.
§Examples
§Margin
A margin is used to create space around UI elements, outside of any defined borders.
let margin = UiRect::all(Val::Auto); // Centers the UI element
§Padding
A padding is used to create space around UI elements, inside of any defined borders.
let padding = UiRect {
left: Val::Px(10.0),
right: Val::Px(20.0),
top: Val::Px(30.0),
bottom: Val::Px(40.0),
};
§Borders
A border is used to define the width of the border of a UI element.
let border = UiRect {
left: Val::Px(10.0),
right: Val::Px(20.0),
top: Val::Px(30.0),
bottom: Val::Px(40.0),
};
Fields§
§left: Val
The value corresponding to the left side of the UI rect.
right: Val
The value corresponding to the right side of the UI rect.
top: Val
The value corresponding to the top side of the UI rect.
bottom: Val
The value corresponding to the bottom side of the UI rect.
Implementations§
source§impl UiRect
impl UiRect
pub const DEFAULT: UiRect = _
pub const ZERO: UiRect = _
sourcepub const fn new(left: Val, right: Val, top: Val, bottom: Val) -> UiRect
pub const fn new(left: Val, right: Val, top: Val, bottom: Val) -> UiRect
Creates a new UiRect
from the values specified.
§Example
let ui_rect = UiRect::new(
Val::Px(10.0),
Val::Px(20.0),
Val::Px(30.0),
Val::Px(40.0),
);
assert_eq!(ui_rect.left, Val::Px(10.0));
assert_eq!(ui_rect.right, Val::Px(20.0));
assert_eq!(ui_rect.top, Val::Px(30.0));
assert_eq!(ui_rect.bottom, Val::Px(40.0));
sourcepub const fn all(value: Val) -> UiRect
pub const fn all(value: Val) -> UiRect
Creates a new UiRect
where all sides have the same value.
§Example
let ui_rect = UiRect::all(Val::Px(10.0));
assert_eq!(ui_rect.left, Val::Px(10.0));
assert_eq!(ui_rect.right, Val::Px(10.0));
assert_eq!(ui_rect.top, Val::Px(10.0));
assert_eq!(ui_rect.bottom, Val::Px(10.0));

sourcepub const fn px(left: f32, right: f32, top: f32, bottom: f32) -> UiRect
pub const fn px(left: f32, right: f32, top: f32, bottom: f32) -> UiRect
Creates a new UiRect
from the values specified in logical pixels.
This is a shortcut for UiRect::new()
, applying Val::Px
to all arguments.
§Example
let ui_rect = UiRect::px(10., 20., 30., 40.);
assert_eq!(ui_rect.left, Val::Px(10.));
assert_eq!(ui_rect.right, Val::Px(20.));
assert_eq!(ui_rect.top, Val::Px(30.));
assert_eq!(ui_rect.bottom, Val::Px(40.));
sourcepub const fn percent(left: f32, right: f32, top: f32, bottom: f32) -> UiRect
pub const fn percent(left: f32, right: f32, top: f32, bottom: f32) -> UiRect
Creates a new UiRect
from the values specified in percentages.
This is a shortcut for UiRect::new()
, applying Val::Percent
to all arguments.
§Example
let ui_rect = UiRect::percent(5., 10., 2., 1.);
assert_eq!(ui_rect.left, Val::Percent(5.));
assert_eq!(ui_rect.right, Val::Percent(10.));
assert_eq!(ui_rect.top, Val::Percent(2.));
assert_eq!(ui_rect.bottom, Val::Percent(1.));
sourcepub fn horizontal(value: Val) -> UiRect
pub fn horizontal(value: Val) -> UiRect
Creates a new UiRect
where left
and right
take the given value,
and top
and bottom
set to zero Val::ZERO
.
§Example
let ui_rect = UiRect::horizontal(Val::Px(10.0));
assert_eq!(ui_rect.left, Val::Px(10.0));
assert_eq!(ui_rect.right, Val::Px(10.0));
assert_eq!(ui_rect.top, Val::ZERO);
assert_eq!(ui_rect.bottom, Val::ZERO);

sourcepub fn vertical(value: Val) -> UiRect
pub fn vertical(value: Val) -> UiRect
Creates a new UiRect
where top
and bottom
take the given value,
and left
and right
are set to Val::ZERO
.
§Example
let ui_rect = UiRect::vertical(Val::Px(10.0));
assert_eq!(ui_rect.left, Val::ZERO);
assert_eq!(ui_rect.right, Val::ZERO);
assert_eq!(ui_rect.top, Val::Px(10.0));
assert_eq!(ui_rect.bottom, Val::Px(10.0));

.
§Example
let ui_rect = UiRect::bottom(Val::Px(10.0));
assert_eq!(ui_rect.left, Val::ZERO);
assert_eq!(ui_rect.right, Val::ZERO);
assert_eq!(ui_rect.top, Val::ZERO);
