Struct ShaderResolver 

pub struct ShaderResolver<'a> { /* private fields */ }

A Wesl import resolver. Maps module paths to actual Wesl shader source.

Implementations

impl<'a> ShaderResolver<'a>

pub fn new( module_path_to_asset_id: &'a HashMap<ModulePath, AssetId<Shader>>, shaders: &'a HashMap<AssetId<Shader>, Shader>, constants_source: &'a str, ) -> ShaderResolver<'a>

Creates a shader resolver with the given map of module paths to shader asset ids, map of shader asset ids to shader source, and the source of the virtual constants module. This resolver is not meant to be long living.

Trait Implementations

impl<'a> Resolver for ShaderResolver<'a>

fn resolve_source( &self, module_path: &ModulePath, ) -> Result<Cow<'_, str>, ResolveError>

Try to resolve a source file identified by a module path.

fn canonical_path(&self, module_path: &ModulePath) -> ModulePath

Get the canonical form of a module path.

fn display_name(&self, module_path: &ModulePath) -> Option<String>

Get the display name of the module path. Implementing this is optional.

fn fs_path(&self, _module_path: &ModulePath) -> Result<PathBuf, ResolveError>

Get the filesystem path of the module path. Implementing this is optional.

fn module_path(&self, _fs_path: &Path) -> Result<ModulePath, ResolveError>

Get the module path of the filesystem path. Implementing this is optional.
