Trait SpriteView 

pub trait SpriteView<'a> {
    // Required methods

A generic view over a sprite or a sprite transformation

Further transformations can be applied to a generic sprite view, or it can be drawn to the screen.

This trait allows to define functions that accept both “original” sprites (i.e. of type Sprite) or their transformations (e.g. of type SpriteViewImpl).

Required Methods

fn width(&self) -> u32

Get the sprite width

fn height(&self) -> u32

Get the sprite height

fn rotate(&'a self, rotation: Rotation) -> SpriteViewImpl<'a>

Apply a rotation to the sprite view

fn flip_horizontally(&'a self, flip_horizontally: bool) -> SpriteViewImpl<'a>

Flip the sprite view horizontally

fn flip_vertically(&'a self, flip_vertically: bool) -> SpriteViewImpl<'a>

Flip the sprite view vertically

fn clip( &'a self, src_x: u32, src_y: u32, width: u32, height: u32, ) -> SpriteViewImpl<'a>

Clip the sprite view to a subregion

fn blit(&self, x: i32, y: i32)

Draw the sprite view to the screen

The sprite is drawn at the point x, y after applying all the transformations in the view.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
