Struct DamageRect 

pub struct DamageRect {
    pub x: f32,
    pub y: f32,
    pub width: f32,
    pub height: f32,
}

An axis-aligned rectangle in f32 space. Coordinate system is up to the caller — the library treats y as “down” only in the sense that DamageRect::bottom returns y + height.

Fields

x: f32

Left edge.

y: f32

Top edge.

width: f32

Width; must be non-negative.

height: f32

Height; must be non-negative.

Implementations

impl DamageRect

pub const fn new(x: f32, y: f32, width: f32, height: f32) -> Self

Construct a new rectangle.

Negative width or height is not rejected but produces nonsense from DamageRect::intersects and DamageRect::union; the caller is responsible for ensuring non-negativity.

pub fn right(&self) -> f32

Right edge (x + width).

pub fn bottom(&self) -> f32

Bottom edge (y + height).

pub fn area(&self) -> f32

Area (width * height).

pub fn intersects(&self, other: &DamageRect) -> bool

Whether self overlaps other (zero-area edge contact returns false).

pub fn union(&self, other: &DamageRect) -> DamageRect

Smallest rectangle that contains both self and other.

pub fn contains_point(&self, px: f32, py: f32) -> bool

Whether the point (px, py) lies inside self. Matches half-open semantics: left/top inclusive, right/bottom exclusive.

Trait Implementations

impl Clone for DamageRect

fn clone(&self) -> DamageRect

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DamageRect

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

Formats the value using the given formatter.

impl Display for DamageRect

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

Formats the value using the given formatter.

impl PartialEq for DamageRect

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