Struct LayoutRect 

pub struct LayoutRect {
    pub x: i32,
    pub y: i32,
    pub width: u16,
    pub height: u16,
}

A rectangle with signed origin and unsigned dimensions.

Used throughout the engine to represent both screen-space regions and floating-window geometry where off-screen coordinates are valid.

Fields

x: i32

y: i32

width: u16

height: u16

Implementations

impl LayoutRect

pub fn center(&self) -> (i32, i32)

Centre point of the rectangle, rounding down on odd dimensions.

pub fn is_empty(&self) -> bool

Check if the rectangle has zero area.

pub fn intersection(&self, other: LayoutRect) -> LayoutRect

Compute the intersection of two rectangles.

pub fn contains<T: Into<i32>>(&self, col: T, row: T) -> bool

Check if a point is inside the rectangle. Generic over coordinate type - accepts both i32 and u16.

pub fn clamp(self, bounds: LayoutRect) -> LayoutRect

pub fn visible_portion(self, bounds: LayoutRect) -> LayoutRect

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

pub fn screen_to_local_point(&self, col: u16, row: u16) -> (i32, i32)

Subtract the rect origin from screen coordinates to get local deltas.

CATEGORY 3 — Scalar Geometry. Pure arithmetic helper for text_renderer.rs and mouse_coord.rs. Returns signed deltas that may be negative (positions outside the rect).
