Struct Material 

pub struct Material { /* private fields */ }

A material manages shader parameters, textures, and pipeline state.

Implementations

impl Material

pub fn new(shader: Arc<ShaderModule>, context: Arc<GraphicsContext>) -> Self

Create a new material with a shader.

pub fn from_source( source: &str, label: Option<&str>, context: Arc<GraphicsContext>, ) -> Self

Create a material from a shader source string.

pub fn set_parameter( &mut self, name: impl Into<String>, value: MaterialParameter, )

Set a parameter by name.

pub fn get_parameter(&self, name: &str) -> Option<&MaterialParameter>

Get a parameter by name.

pub fn set_texture(&mut self, name: impl Into<String>, texture: MaterialTexture)

Set a texture by name.

pub fn get_texture(&self, name: &str) -> Option<&MaterialTexture>

Get a texture by name.

pub fn set_pipeline_state(&mut self, state: PipelineState)

Set the pipeline state.

pub fn pipeline_state(&self) -> &PipelineState

Get the pipeline state.

pub fn shader(&self) -> &ShaderModule

Get the shader module.

pub fn bind<'a>(&'a mut self, pass: &mut RenderPass<'a>, bind_group_index: u32)

Bind this material’s resources to a render pass.

This will update GPU resources if needed and set the bind group.

Arguments

• pass - The render pass to bind to
• bind_group_index - The bind group index (default is usually 0)

pub fn bind_group_layout(&mut self) -> &BindGroupLayout

Get the bind group layout (creates it if needed).

This is useful when creating render pipelines.
