Struct Preprocessor

pub struct Preprocessor<R: Resolver, F: ResolveFn> {
    pub resolver: R,
    pub preprocess: F,
}

A WESL module preprocessor.

The preprocess function will be called each time the WESL compiler tries to load a module.

Fields

resolver: R

preprocess: F

Implementations

impl<R: Resolver, F: ResolveFn> Preprocessor<R, F>

pub fn new(resolver: R, preprocess: F) -> Self

Create a new resolver that runs the preprocessing function before each call to Resolver::resolve_module.

Trait Implementations

impl<R: Resolver, F: ResolveFn> Resolver for Preprocessor<R, F>

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

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

fn source_to_module( &self, source: &str, path: &ModulePath, ) -> Result<TranslationUnit, ResolveError>

Convert a source file into a syntax tree.

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

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

fn resolve_module( &self, path: &ModulePath, ) -> Result<TranslationUnit, ResolveError>

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