Struct ClipRect 

pub struct ClipRect {
    pub x0: i64,
    pub y0: i64,
    pub x1: i64,
    pub y1: i64,
}

An integer-bounded clip rectangle: [x0, x1) × [y0, y1).

Fields

x0: i64

Inclusive left bound.

y0: i64

Inclusive top bound.

x1: i64

Exclusive right bound.

y1: i64

Exclusive bottom bound.

Implementations

impl ClipRect

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

A clip covering the whole framebuffer [0, width) × [0, height).

pub fn from_rect(x: i64, y: i64, w: i64, h: i64) -> Self

Construct from a position and size (negative sizes yield an empty clip).

pub fn is_empty(&self) -> bool

Returns true if the clip has zero or negative area.

pub fn intersect(&self, other: &ClipRect) -> ClipRect

Intersect with other, returning the overlapping clip.

pub fn contains(&self, x: i64, y: i64) -> bool

Returns true if pixel (x, y) lies within the clip.
