Struct DirtyRegion 

pub struct DirtyRegion {
    pub start_frame: u64,
    pub end_frame: u64,
}

A contiguous range of frames that require re-rendering.

Fields

start_frame: u64

First dirty frame (inclusive).

end_frame: u64

Last dirty frame (exclusive).

Implementations

impl DirtyRegion

pub fn new(start_frame: u64, end_frame: u64) -> Self

Create a new dirty region.

If end_frame <= start_frame the region is normalised to a single-frame region [start_frame, start_frame + 1).

pub fn overlaps(&self, other: &DirtyRegion) -> bool

Returns true when the two regions overlap or are adjacent.

pub fn merge(&self, other: &DirtyRegion) -> DirtyRegion

Merge two regions into a bounding region covering both.

pub fn frame_count(&self) -> u64

Number of frames covered by this region.

pub fn contains(&self, frame: u64) -> bool

Returns true when frame falls inside this region.

Trait Implementations

impl Clone for DirtyRegion

fn clone(&self) -> DirtyRegion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DirtyRegion

impl Debug for DirtyRegion

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

Formats the value using the given formatter.

impl Eq for DirtyRegion

impl PartialEq for DirtyRegion

fn eq(&self, other: &DirtyRegion) -> 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.
