impl Default for VlConvertModuleLoader

fn default() -> Self

Returns the “default value” for a type.

impl ModuleLoader for VlConvertModuleLoader

fn resolve( &self, specifier: &str, referrer: &str, _kind: ResolutionKind, ) -> Result<ModuleSpecifier, Error>

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_dyn_import: bool, _requested_module_type: RequestedModuleType, ) -> ModuleLoadResponse

Given ModuleSpecifier, load its source code.

fn prepare_load( &self, _module_specifier: &Url, _maybe_referrer: Option<String>, _is_dyn_import: bool, ) -> Pin<Box<dyn Future<Output = Result<(), Error>>>>

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

fn code_cache_ready( &self, _module_specifier: Url, _hash: u64, _code_cache: &[u8], ) -> Pin<Box<dyn Future<Output = ()>>>

Called when new v8 code cache is available for this module. Implementors can store the provided code cache for future executions of the same module.

fn purge_and_prevent_code_cache(&self, _module_specifier: &str)

Called when V8 code cache should be ignored for this module. This can happen if eg. module causes a V8 warning, like when using deprecated import assertions. Implementors should make sure that the code cache for this module is purged and not saved anymore.

fn get_source_map(&self, _file_name: &str) -> Option<Vec<u8>>

Returns a source map for given file_name.

fn get_source_mapped_source_line( &self, _file_name: &str, _line_number: usize, ) -> Option<String>

fn get_host_defined_options<'s>( &self, _scope: &mut HandleScope<'s>, _name: &str, ) -> Option<Local<'s, Data>>

Implementors can attach arbitrary data to scripts and modules by implementing this method. V8 currently requires that the returned data be a v8::PrimitiveArray.
