Struct StandardResolver 

pub struct StandardResolver { /* private fields */ }

The resolver that implements the WESL standard.

It resolves modules in external packages registered with Self::add_package and modules in the local package with the filesystem.

Implementations

impl StandardResolver

pub fn new(base: impl AsRef<Path>) -> Self

Create a new resolver.

base is the root directory which absolute paths refer to.

pub fn add_package(&mut self, pkg: &'static CodegenPkg)

Add an external package.

pub fn add_constant(&mut self, name: impl ToString, value: f64)

Add a numeric constant.

Numeric constants live WESL’s special package named constants. This package is virtual, meaning it doesn’t exist on the filesystem. Constants can be accessed by importing them: import constants::MY_CONSTANT;. All constants are of type AbstractFloat, which can be implicitly converted to all scalar types.

Trait Implementations

impl Resolver for StandardResolver

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

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

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

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

fn fs_path(&self, path: &ModulePath) -> Option<PathBuf>

Get the filesystem path of the module path. Implementing this is optional. Used by build scripts for dependency tracking.

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

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