pub struct ScreenRect(Vec2, Vec2);

A rectangle on the screen.

Tuple Fields

0: Vec2

1: Vec2

Implementations

impl ScreenRect

pub fn full() -> Self

pub fn from_points(a: Vec2, b: Vec2) -> Self

Creates a new screen rectangle from two arbitrary points which lie between [-1, -1] and [1, 1].

See Self::new.

pub fn new(bottom_left: Vec2, top_right: Vec2) -> Self

Arguments

• bottom_left - coordinates of the bottom left corner of the rectangle. Bottom-left corner has coordinates [-1, -1] and top-right corner has coordinates [1, 1].

• top_right - see bottom_left

Panics

• If one of the corners is outside of screen space boundaries.

• If bottom_left corner is to the right or to the top from top_right corner.

pub fn as_array(&self) -> [f32; 4]

Returns array of edge coordinates corresponding to (in order):

• X coordinate of the left edge.
• X coordinate of the right edge.
• Y coordinate of the bottom edge.
• Y coordinate of the top edge.

pub fn left(&self) -> f32

X coordinate of the left edge.

pub fn right(&self) -> f32

X coordinate of the right edge.

pub fn bottom(&self) -> f32

Y coordinate of the bottom edge.

pub fn top(&self) -> f32

Y coordinate of the top edge.

pub fn size(&self) -> Vec2

Returns size of the rectangle. Full screen size is [2., 2.].

Trait Implementations

impl Clone for ScreenRect

fn clone(&self) -> ScreenRect
