Implementations

impl Extension

pub fn builder(name: &'static str) -> ExtensionBuilder

pub fn builder_with_deps( name: &'static str, deps: &'static [&'static str] ) -> ExtensionBuilder

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.

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>

pub fn init_ops(&mut self) -> Option<Vec<OpDecl>>

Called at JsRuntime startup to initialize ops in the isolate.

pub fn init_state(&self, state: &mut OpState)

Allows setting up the initial op-state of an isolate at startup.

pub fn init_middleware(&mut self) -> Option<Box<OpMiddlewareFn>>

init_middleware lets us middleware op registrations, it’s called before init_ops

pub fn init_event_loop_middleware( &mut self ) -> Option<Box<dyn Fn(Rc<RefCell<OpState>>, &mut Context<'_>) -> bool>>

pub fn run_event_loop_middleware( &self, op_state_rc: Rc<RefCell<OpState>>, cx: &mut Context<'_> ) -> bool

pub fn enabled(self, enabled: bool) -> Self

pub fn disable(self) -> Self
