#[repr(C)]
pub struct Promise(_);

Methods

impl Promise

An instance of the built-in Promise constructor (ES6 draft).

pub fn state(&mut self) -> PromiseState

Returns the value of the [PromiseState] field.

pub fn has_handler(&mut self) -> bool

Returns true if the promise has at least one derived promise, and therefore resolve/reject handlers (including default handler).

pub fn result<'sc>(
    &mut self,
    _scope: &mut HandleScope<'sc>
) -> Local<'sc, Value>

Returns the content of the [[PromiseResult]] field. The Promise must not be pending.

pub fn catch<'sc>(
    &mut self,
    context: Local<'sc, Context>,
    handler: Local<'sc, Function>
) -> Option<Local<'sc, Promise>>

Register a rejection handler with a promise.

See Self::then2.

pub fn then<'sc>(
    &mut self,
    context: Local<'sc, Context>,
    handler: Local<'sc, Function>
) -> Option<Local<'sc, Promise>>

Register a resolution handler with a promise.

See Self::then2.

pub fn then2<'sc>(
    &mut self,
    context: Local<'sc, Context>,
    on_fulfilled: Local<'sc, Function>,
    on_rejected: Local<'sc, Function>
) -> Option<Local<'sc, Promise>>

Register a resolution/rejection handler with a promise. The handler is given the respective resolution/rejection value as an argument. If the promise is already resolved/rejected, the handler is invoked at the end of turn.
