Type Alias ModuleMetadataHook 

pub type ModuleMetadataHook = Option<unsafe extern "C" fn(*mut JSContext, Handle<Value>, Handle<*mut JSObject>) -> bool>;

The module metadata hook.

See: https://tc39.es/ecma262/#sec-hostgetimportmetaproperties

Populate the |metaObject| object returned when import.meta is evaluated in the context of the script or module with private value |privateValue|.

This is based on the spec’s HostGetImportMetaProperties hook but defines properties on the meta object directly rather than returning a list.

Aliased Type

pub enum ModuleMetadataHook {
    None,
    Some(unsafe extern "C" fn(*mut JSContext, Handle<Value>, Handle<*mut JSObject>) -> bool),
}

Variants

None

No value.

Some(unsafe extern "C" fn(*mut JSContext, Handle<Value>, Handle<*mut JSObject>) -> bool)

Some value of type T.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
