Enum webrender_api::DirtyRect

source ·
pub enum DirtyRect<T: Copy, U> {
    All,
    Partial(Box2D<T, U>),
}
Expand description

The possible states of a Dirty rect.

This exists because people kept getting confused with Option<Box2D>.

Variants§

§

All

Everything is Dirty, equivalent to Partial(image_bounds)

§

Partial(Box2D<T, U>)

Some specific amount is dirty

Implementations§

source§

impl<T, U> DirtyRect<T, U>
where T: Copy + Clone + PartialOrd + PartialEq + Add<T, Output = T> + Sub<T, Output = T> + Zero,

source

pub fn empty() -> Self

Creates an empty DirtyRect (indicating nothing is invalid)

source

pub fn is_empty(&self) -> bool

Returns whether the dirty rect is empty

source

pub fn replace_with_empty(&mut self) -> Self

Replaces self with the empty rect and returns the old value.

source

pub fn map<F>(self, func: F) -> Self
where F: FnOnce(Box2D<T, U>) -> Box2D<T, U>,

Maps over the contents of Partial.

source

pub fn union(&self, other: &Self) -> Self

Unions the dirty rects.

source

pub fn intersection(&self, other: &Self) -> Self

Intersects the dirty rects.

source

pub fn to_subrect_of(&self, rect: &Box2D<T, U>) -> Box2D<T, U>

Converts the dirty rect into a subrect of the given one via intersection.
