Struct FsModuleLoader

pub struct FsModuleLoader { /* private fields */ }

The loader is used to manage the process of creating an in-memory model from file-system resources.

A Module Loader is therefore responsible for:

1. finding the resource that contains a module definition,
2. parsing the source into an in-memory representation,
3. caching the loaded module, and it’s source, for future use.

Implementations

impl FsModuleLoader

pub fn with_resolver(self, resolver: FsModuleResolver) -> Self

pub fn with_reporter(self, reporter: Box<dyn Reporter>) -> Self

pub fn load_from_file( &mut self, file: PathBuf, cache: &mut impl ModuleStore, recursive: bool, ) -> Result<Identifier, Error>

Load a module from the source in file.

pub fn load_from_reader( &mut self, reader: &mut dyn Read, cache: &mut impl ModuleStore, recursive: bool, ) -> Result<Identifier, Error>

Load a module reading the source from reader.

Trait Implementations

impl Debug for FsModuleLoader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FsModuleLoader

fn default() -> Self

Returns the “default value” for a type.

impl ModuleLoader for FsModuleLoader

fn load( &mut self, name: &Identifier, from: Option<FileId>, cache: &mut impl ModuleStore, recursive: bool, ) -> Result<Identifier, Error>

Resolve name into a resource identifier (URL) and parse into memory. The loader will check the store first to see if the module is already loaded, and will add the module into the store after parsing. The value of recursive tells the loader whether to also load the module’s dependencies as well.

fn resolver(&self) -> &impl ModuleResolver

Returns the instance of ModuleResolver used by this loader.
