Struct Rect 

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

An axis-aligned rectangle with u32 coordinates.

Uses u32 rather than u16 to avoid overflow bugs that affect other TUI libraries on large terminals. All coordinates are in terminal columns and rows, with (0, 0) at the top-left.

Note: Rect::right and Rect::bottom return exclusive bounds (one past the last column/row), consistent with Rust range conventions.

Fields

x: u32

Left edge column, inclusive.

y: u32

Top edge row, inclusive.

width: u32

Width in terminal columns.

height: u32

Height in terminal rows.

Implementations

impl Rect

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

Create a new rectangle from position and size.

pub const fn area(&self) -> u32

Total area in cells (width * height).

pub const fn right(&self) -> u32

Exclusive right edge (x + width).

This is one column past the last column in the rectangle.

pub const fn bottom(&self) -> u32

Exclusive bottom edge (y + height).

This is one row past the last row in the rectangle.

pub const fn is_empty(&self) -> bool

Returns true if the rectangle has zero area (width or height is zero).

Trait Implementations

impl Clone for Rect

fn clone(&self) -> Rect

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Rect

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

Formats the value using the given formatter.

impl Default for Rect

fn default() -> Rect

Returns the “default value” for a type.

impl Hash for Rect

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Rect

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