Struct Rect 

pub struct Rect {
    pub x: u16,
    pub y: u16,
    pub w: u16,
    pub h: u16,
}

An axis-aligned rectangle in a discrete cell grid. x/y are the top-left origin; w/h are width/height. A zero-area rect is legal (it models a pane squeezed out of a too-small window) but Rect::is_empty flags it so renderers can skip it.

Fields

x: u16

y: u16

w: u16

h: u16

Implementations

impl Rect

pub const fn new(x: u16, y: u16, w: u16, h: u16) -> Self

A rect at the origin with the given size — the usual window-root bounding box (Rect::new(0, 0, cols, rows)).

pub const fn sized(w: u16, h: u16) -> Self

A rect rooted at the origin (x = y = 0).

pub const fn right(self) -> u32

The x coordinate one past the right edge (x + w). Widened to u32 so a full-width rect at a high x cannot wrap.

pub const fn bottom(self) -> u32

The y coordinate one past the bottom edge (y + h).

pub const fn area(self) -> u32

Area in cells.

pub const fn is_empty(self) -> bool

True when either dimension is zero — the pane has been squeezed to nothing and a renderer should skip it.

pub fn contains(self, px: u16, py: u16) -> bool

True when (px, py) falls inside the rect (right/bottom edges exclusive — adjacent rects never both claim a boundary cell).
