pub fn init_ops(&mut self) -> Option<Vec<(&'static str, Box<OpFn>)>>

Called at JsRuntime startup to initialize ops in the isolate.

pub fn init_state(&self, state: &mut OpState) -> Result<(), AnyError>

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
