Struct deno_core::FsModuleLoader

pub struct FsModuleLoader;

Basic file system module loader.

Note that this loader will block event loop when loading file as it uses synchronous FS API from standard library.

Trait Implementations

impl ModuleLoader for FsModuleLoader

fn resolve(
    &self,
    specifier: &str,
    referrer: &str,
    _is_main: bool
) -> Result<ModuleSpecifier, AnyError>

Returns an absolute URL. When implementing an spec-complaint VM, this should be exactly the algorithm described here: https://html.spec.whatwg.org/multipage/webappapis.html#resolve-a-module-specifier

fn load(
    &self,
    module_specifier: &ModuleSpecifier,
    _maybe_referrer: Option<ModuleSpecifier>,
    _is_dynamic: bool
) -> Pin<Box<ModuleSourceFuture>>

Given ModuleSpecifier, load its source code.

fn prepare_load(
    &self,
    _op_state: Rc<RefCell<OpState>>,
    _load_id: ModuleLoadId,
    _module_specifier: &ModuleSpecifier,
    _maybe_referrer: Option<String>,
    _is_dyn_import: bool
) -> Pin<Box<dyn Future<Output = Result<(), AnyError>>>>

This hook can be used by implementors to do some preparation work before starting loading of modules.
