Struct ClipStack 

pub struct ClipStack { /* private fields */ }

A stack of nested clip rectangles.

The effective clip is always the intersection of every pushed rectangle, maintained incrementally as current.

Implementations

impl ClipStack

pub fn new(width: u32, height: u32) -> Self

Create a stack whose base clip covers the whole framebuffer.

pub fn current(&self) -> ClipRect

The current effective clip (intersection of all pushed rects).

pub fn push(&mut self, clip: ClipRect)

Push clip, intersecting it with the current effective clip.

pub fn pop(&mut self)

Pop the most recently pushed clip. The base clip is never popped.

pub fn depth(&self) -> usize

Number of clips on the stack (including the base).
