Trait Implementations

impl Shader for Shape

const FILE_PATH: &'static str = "shape.wgsl"

Path of the shader’s .wgsl file.

fn from_device(device: &Device) -> Result<Self, ComposerError>

Instantiates this Shader from a gpu device.

fn src() -> String

This shader’s sources (before dependency and macro resolution).

fn naga_module() -> Result<Module, ComposerError>

The naga module built from this shader.

fn absolute_path() -> Option<PathBuf>

The absolute path of this wgsl shader source file.

fn compose(composer: &mut Composer) -> Result<(), ComposerError>

Add to composer the composable module definition of Self (if there are any) and all its shader dependencies .

fn watch_sources(state: &mut HotReloadState) -> Result<()>

Registers all the source files, for Self and all its shader dependencies, for change detection.

fn needs_reload(state: &HotReloadState) -> bool

Checks if this shader (or any of its dependencies) need to be reloaded due to a change from disk.

fn flat_wgsl() -> Result<String, ComposerError>

This shader’s WGSL sources as a single file (after dependency and macro resolution).

fn composer() -> Result<Composer, ComposerError>

A composer filled with the module definition of Self (if there is any) and all its shader dependencies.

fn set_absolute_path(path: PathBuf)

Registers in the global ShaderRegistry known absolute path for this shader.

fn reload_if_changed( &mut self, device: &Device, state: &HotReloadState, ) -> Result<bool, ComposerError>

Reloads this shader if it on any of its dependencies have been changed from disk.
