Struct AtlasTextureDescriptor

pub struct AtlasTextureDescriptor {
    pub offset_px: UVec2,
    pub size_px: UVec2,
    pub layer_index: u32,
    pub frame_index: u32,
    pub modes: TextureModes,
}

A texture inside the atlas.

Fields

offset_px: UVec2

The top left offset of texture in the atlas.

size_px: UVec2

The size of the texture in the atlas.

layer_index: u32

The index of the layer within the atlas that this AtlasTexture belongs to.

frame_index: u32

The index of this frame within the layer.

modes: TextureModes

Various toggles of texture modes.

Implementations

impl AtlasTextureDescriptor

pub fn uv(&self, uv: Vec2, atlas_size: UVec2) -> Vec3

Transform the given uv coordinates for this texture’s address mode and placement in the atlas of the given size.

pub fn constrain_clip_coords_to_texture_space( &self, clip_pos: Vec2, atlas_size: UVec2, ) -> Vec2

Constrain the input clip_pos to be within the bounds of this texture within its atlas, in texture space.

pub fn constrain_clip_coords(&self, clip_pos: Vec2, atlas_size: UVec2) -> Vec2

Constrain the input clip_pos to be within the bounds of this texture within its atlas.

pub fn origin(&self) -> Origin3d

Returns the frame of this texture as a [wgpu::Origin3d].

pub fn size_as_extent(&self) -> Extent3d

Returns the frame of this texture as a [wgpu::Extent3d].

Trait Implementations

impl Clone for AtlasTextureDescriptor

fn clone(&self) -> AtlasTextureDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AtlasTextureDescriptor

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

Formats the value using the given formatter.

impl Default for AtlasTextureDescriptor

fn default() -> AtlasTextureDescriptor

Returns the “default value” for a type.

impl PartialEq for AtlasTextureDescriptor

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

impl SlabItem for AtlasTextureDescriptor

where UVec2: SlabItem, u32: SlabItem, TextureModes: SlabItem,

const SLAB_SIZE: usize = 8usize

The number of u32s this type occupies in a slab of &[u32].

fn read_slab(index: usize, slab: &[u32]) -> Self

Read the type out of the slab at index.

fn write_slab(&self, index: usize, slab: &mut [u32]) -> usize

Write the type into the slab at starting index and return the new index.
