Struct BlitPlanner 

pub struct BlitPlanner<const N: usize> { /* private fields */ }

Collects dirty rectangles for a frame and optionally coalesces them.

The planner stores up to N rectangles in a stack-allocated buffer. Call Self::add to register a region that changed during rendering and Self::rects to obtain the batched list for flushing. After presenting the frame, call Self::clear to reuse the planner for the next frame.

Adds beyond N are silently dropped, but Self::overflowed flips to true so callers driving a dirty-rect present path know the rect set is incomplete and can fall back to a full-frame repaint for that frame.

Implementations

impl<const N: usize> BlitPlanner<N>

pub fn new() -> Self

Create an empty planner.

pub fn add(&mut self, rect: Rect)

Record a dirty rectangle.

pub fn rects(&self) -> &[Rect]

Return all accumulated rectangles.

pub fn overflowed(&self) -> bool

Whether Self::add dropped a rect because the planner was full.

pub fn clear(&mut self)

Remove all stored rectangles.

Trait Implementations

impl<const N: usize> Default for BlitPlanner<N>

fn default() -> Self

Returns the “default value” for a type.
