Struct ShaderStore 

pub struct ShaderStore { /* private fields */ }

Manages custom user-defined fragment shaders. Each shader gets its own render pipeline and uniform buffer.

Implementations

impl ShaderStore

pub fn new_headless(device: &Device, format: TextureFormat) -> Self

Create a shader store for headless testing.

pub fn new(gpu: &GpuContext) -> Self

pub fn create(&mut self, device: &Device, id: u32, _name: &str, source: &str)

Compile a custom shader from user-provided WGSL fragment source. The source must contain a @fragment fn fs_main(in: VertexOutput) -> @location(0) vec4<f32>. Standard declarations (camera, texture, lighting, vertex shader) are prepended automatically. Custom uniforms are available as shader_params.values[0..15] (vec4 array).

pub fn set_param(&mut self, id: u32, index: u32, x: f32, y: f32, z: f32, w: f32)

Set a vec4 user parameter slot for a shader. Index 0-13 maps to WGSL values[0..13]. Internally offset by BUILTIN_SLOTS so user slot 0 → param_data[8..11].

pub fn flush( &mut self, queue: &Queue, time: f32, delta: f32, resolution: [f32; 2], mouse: [f32; 2], )

Flush uniform buffers to GPU, auto-injecting built-in values. Built-ins (time, delta, resolution, mouse) are written every frame for all shaders.

pub fn get_pipeline(&self, id: u32) -> Option<&RenderPipeline>

Get the pipeline for a custom shader.

pub fn get_bind_group(&self, id: u32) -> Option<&BindGroup>

Get the uniform bind group for a custom shader (group 3).
