Implementations
sourceimpl Extension
impl Extension
pub fn builder() -> ExtensionBuilder
sourcepub fn init_js(&self) -> &[(&'static str, &'static str)]
pub fn init_js(&self) -> &[(&'static str, &'static str)]
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.
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(&self, state: &mut OpState) -> Result<(), Error>
pub fn init_state(&self, state: &mut OpState) -> Result<(), Error>
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
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
