Struct TextureStore 

pub struct TextureStore { /* private fields */ }

Handle-based texture store. Loads PNGs, uploads to GPU, returns opaque handles.

Implementations

impl TextureStore

pub fn new() -> Self

pub fn load( &mut self, gpu: &GpuContext, bind_group_layout: &BindGroupLayout, path: &Path, ) -> Result<TextureId>

Load a texture from a PNG file. Returns the texture handle. If the same path was already loaded, returns the cached handle.

pub fn create_solid_color( &mut self, device: &Device, queue: &Queue, bind_group_layout: &BindGroupLayout, name: &str, r: u8, g: u8, b: u8, a: u8, ) -> TextureId

Create a solid-color 1x1 texture. Useful for placeholder sprites.

pub fn upload_raw( &mut self, device: &Device, queue: &Queue, bind_group_layout: &BindGroupLayout, id: TextureId, pixels: &[u8], width: u32, height: u32, )

Upload raw RGBA pixel data as a texture with a pre-assigned ID. Used for procedurally generated textures (e.g., built-in font).

pub fn upload_raw_linear( &mut self, device: &Device, queue: &Queue, bind_group_layout: &BindGroupLayout, id: TextureId, pixels: &[u8], width: u32, height: u32, )

Upload raw RGBA pixels as a linear (non-sRGB) texture with bilinear filtering. Use this for distance field atlases (MSDF, SDF) where values must be sampled linearly.

pub fn get_bind_group(&self, id: TextureId) -> Option<&BindGroup>

Get the bind group for a texture handle (regular textures and render targets).

pub fn get_dimensions(&self, id: TextureId) -> Option<(u32, u32)>

Get texture dimensions (regular textures and render targets).

pub fn register_render_target( &mut self, device: &Device, bind_group_layout: &BindGroupLayout, id: TextureId, view: &TextureView, width: u32, height: u32, )

Register a render target’s TextureView as a samplable texture.

The texture itself is owned by RenderTargetStore; we only create the bind group here. wgpu’s internal reference counting keeps the GPU resource alive for as long as the bind group exists.

pub fn unregister_render_target(&mut self, id: TextureId)

Remove a render target’s bind group. Call after destroying the render target.
