impl Extension
pub fn builder(name: &'static str) -> ExtensionBuilder
pub fn builder_with_deps( name: &'static str, deps: &'static [&'static str] ) -> ExtensionBuilder
sourcepub fn check_dependencies(&self, previous_exts: &[Extension])
pub fn check_dependencies(&self, previous_exts: &[Extension])
Check if dependencies have been loaded, and errors if either:
- The extension is depending on itself or an extension with the same name.
- A dependency hasn’t been loaded yet.
sourcepub fn get_js_sources(&self) -> Option<&Vec<ExtensionFileSource>>
pub fn get_js_sources(&self) -> Option<&Vec<ExtensionFileSource>>
returns JS source code to be loaded into the isolate (either at snapshotting, or at startup). as a vector of a tuple of the file name, and the source code.
pub fn get_esm_sources(&self) -> Option<&Vec<ExtensionFileSource>>
pub fn get_esm_entry_point(&self) -> Option<&'static str>
sourcepub fn init_ops(&mut self) -> Option<Vec<OpDecl>>
pub fn init_ops(&mut self) -> Option<Vec<OpDecl>>
Called at JsRuntime startup to initialize ops in the isolate.
sourcepub fn init_state(&mut self, state: &mut OpState)
pub fn init_state(&mut self, state: &mut OpState)
Allows setting up the initial op-state of an isolate at startup.
sourcepub fn init_middleware(&mut self) -> Option<Box<OpMiddlewareFn>>
pub fn init_middleware(&mut self) -> Option<Box<OpMiddlewareFn>>
init_middleware lets us middleware op registrations, it’s called before init_ops
