Struct Rect 

pub struct Rect {
    pub x: u16,
    pub y: u16,
    pub width: u16,
    pub height: u16,
}

A rectangle defined by position and size.

Fields

x: u16

X coordinate (column) of the top-left corner.

y: u16

Y coordinate (row) of the top-left corner.

width: u16

Width in columns.

height: u16

Height in rows.

Implementations

impl Rect

pub const ZERO: Self

Zero-sized rectangle.

pub const fn new(x: u16, y: u16, width: u16, height: u16) -> Self

Create a new rectangle.

pub const fn from_size(width: u16, height: u16) -> Self

Create a rectangle from a terminal size (full screen).

pub const fn area(&self) -> u32

Get the area (number of cells).

pub const fn is_empty(&self) -> bool

Check if the rectangle is empty.

pub const fn right(&self) -> u16

Get the right edge (exclusive).

pub const fn bottom(&self) -> u16

Get the bottom edge (exclusive).

pub const fn contains(&self, x: u16, y: u16) -> bool

Check if a point is inside the rectangle.

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

Check if this rectangle intersects with another.

pub const fn shrink(&self, margin: u16) -> Self

Shrink the rectangle by a margin on all sides.

pub fn split_horizontal(&self, at: u16) -> (Self, Self)

Split horizontally at a given column offset.

pub fn split_vertical(&self, at: u16) -> (Self, Self)

Split vertically at a given row offset.

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.
