Trait wlambda::compiler::ModuleResolver

pub trait ModuleResolver {
    fn resolve(
        &self, 
        global: GlobalEnvRef, 
        path: &[String], 
        import_file_path: Option<&str>
    ) -> Result<SymbolTable, ModuleLoadError<'_>>;
}

This trait is responsible for loading modules and returning a collection of name->value mappings for a module name.

See also GlobalEnv::set_resolver() about how to configure the global environment to use you trait implementation.

There is a default implementation named LocalFileModuleResolver, which loads the modules from files.

Required methods

fn resolve(
    &self,
    global: GlobalEnvRef,
    path: &[String],
    import_file_path: Option<&str>
) -> Result<SymbolTable, ModuleLoadError<'_>>

Resolves the path to a HashMap of names -> VVal. Where you obtain this mapping from is completely up to you. You can statically define these, load them from a JSON file, load them by executing another WLambda script or whatever you fancy.

See LocalFileModuleResolver as example on how to implement this.
