Struct deno_core::StaticModuleLoader

pub struct StaticModuleLoader { /* private fields */ }

A module loader that you can pre-load a number of modules into and resolve from. Useful for testing and embedding situations where the filesystem and snapshot systems are not usable or a good fit.

Implementations

impl StaticModuleLoader

pub fn new( from: impl IntoIterator<Item = (ModuleSpecifier, impl IntoModuleCodeString)> ) -> Self

Create a new StaticModuleLoader from an Iterator of specifiers and code.

pub fn with(specifier: ModuleSpecifier, code: impl IntoModuleCodeString) -> Self

Create a new StaticModuleLoader from a single code item.

Trait Implementations

impl Default for StaticModuleLoader

fn default() -> StaticModuleLoader

Returns the “default value” for a type.

impl ModuleLoader for StaticModuleLoader

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: &ModuleSpecifier, _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: &ModuleSpecifier, _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.
