Struct FrameDamage 

pub struct FrameDamage {
    pub generation: u64,
    pub recent: Arc<[(u64, Arc<[PixelRect]>)]>,
}

Where a frame differs from the ones its engine made before it: a view that drew one of those repaints, and uploads, only there.

Fields

generation: u64

The frame’s place in its engine’s sequence. A frame whose recent does not reach back to the one a view drew is new throughout to it.

recent: Arc<[(u64, Arc<[PixelRect]>)]>

What each recent generation changed from the one before it, newest first, down to some generation after the oldest still known.

Implementations

impl FrameDamage

pub fn since(&self, drawn: u64) -> Option<Vec<PixelRect>>

What changed since generation drawn: nothing when it is this frame’s, None when not known.

Trait Implementations

impl Clone for FrameDamage

fn clone(&self) -> FrameDamage

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FrameDamage

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for FrameDamage

fn default() -> FrameDamage

Returns the “default value” for a type.

impl PartialEq for FrameDamage

fn eq(&self, other: &FrameDamage) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
