Implementations§

source§

impl<Data: ToNapiValue, Resolver: FnOnce(Env) -> Result<Data>> JsDeferred<Data, Resolver>

source

pub fn resolve(self, resolver: Resolver)

Consumes the deferred, and resolves the promise. The provided function will be called from the JavaScript thread, and should return the resolved value.

source

pub fn reject(self, error: Error)

Consumes the deferred, and rejects the promise with the provided error.
