Struct blit::geom::SubRect

pub struct SubRect {
    pub x: i32,
    pub y: i32,
    pub size: Size,
}

Helper struct for defining sub-rectangles.

A sub-rectangle is a rectangle that’s part of a bigger rectangle.

Fields

x: i32

X offset in pixels.

y: i32

Y offset in pixels.

size: Size

Size of the rectangle in pixels.

Implementations

impl SubRect

pub fn new<X, Y, S>(x: X, y: Y, size: S) -> Self

where X: ToPrimitive, Y: ToPrimitive, S: Into<Size>,

Create a new sub-rectangle.

pub fn from_size<S>(size: S) -> Self

where S: Into<Size>,

Construct from a size with zero coordinates.

pub fn shift<X, Y>(&self, new_x: X, new_y: Y) -> Self

where X: ToPrimitive, Y: ToPrimitive,

Shift the left and top position while keeping the right and bottom position at the same spot.

pub fn width(&self) -> u32

Width as u32.

pub fn height(&self) -> u32

Height as u32.

pub fn right(&self) -> i32

Right position, x + width.

pub fn bottom(&self) -> i32

Bottom position, y + height.

pub fn as_slice(&self) -> (i32, i32, u32, u32)

(x, y, width, height) slice.

Trait Implementations

impl Clone for SubRect

fn clone(&self) -> SubRect

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SubRect

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

Formats the value using the given formatter.

impl<X, Y, W, H> From<(X, Y, W, H)> for SubRect

where X: ToPrimitive, Y: ToPrimitive, W: ToPrimitive, H: ToPrimitive,

fn from((x, y, width, height): (X, Y, W, H)) -> Self

Converts to this type from the input type.

impl PartialEq for SubRect

fn eq(&self, other: &SubRect) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
