Struct deno_core::NoopModuleLoader

pub struct NoopModuleLoader;

Placeholder structure used when creating a runtime that doesn’t support module loading.

Trait Implementations

impl ModuleLoader for NoopModuleLoader

fn resolve(
    &self,
    _specifier: &str,
    _referrer: &str,
    _is_main: bool
) -> 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
) -> Pin<Box<ModuleSourceFuture>>

Given ModuleSpecifier, load its source code.

fn prepare_load(
    &self,
    _op_state: Rc<RefCell<OpState>>,
    _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.
