Struct LastSizeView

pub struct LastSizeView<T> {
    pub view: T,
    pub size: Vec2,
}

Wrapper around a view that remembers its size.

Fields

view: T

Wrapped view.

size: Vec2

Cached size from the last layout() call.

Implementations

impl<T> LastSizeView<T>

pub fn new(view: T) -> Self

Wraps the given view.

pub fn get_inner(&self) -> &T

Gets access to the inner view.

pub fn get_inner_mut(&mut self) -> &mut T
