Struct Rect 

pub struct Rect {
    pub x: u32,
    pub y: u32,
    pub width: u32,
    pub height: u32,
}

An axis-aligned rectangle in sensor-buffer coordinates.

Fields

x: u32

Left edge (first column), in pixels.

y: u32

Top edge (first row), in pixels.

width: u32

Width in pixels.

height: u32

Height in pixels.

Implementations

impl Rect

pub const fn new(x: u32, y: u32, width: u32, height: u32) -> Rect

Rect with top-left corner (x, y) and the given size.

pub fn from_ltrb(left: u32, top: u32, right: u32, bottom: u32) -> Option<Rect>

Rect from left/top/right/bottom edges (exclusive right/bottom). Returns None if inverted.

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

Rect covering a whole width x height buffer, anchored at (0, 0).

pub fn right(&self) -> u32

Exclusive right edge (x + width, saturating).

pub fn bottom(&self) -> u32

Exclusive bottom edge (y + height, saturating).

pub fn is_empty(&self) -> bool

True if the rect covers no pixels (zero width or height).

pub fn area(&self) -> u64

Number of pixels covered (width * height).

pub fn intersect(&self, o: &Rect) -> Option<Rect>

Overlap of two rects, or None if they do not overlap.

pub fn contains_rect(&self, o: &Rect) -> bool

True if o lies entirely inside self.

pub fn clamp_to(&self, width: u32, height: u32) -> Rect

Clamp to a width x height buffer, returning an empty rect if fully outside.
