Enum v8::PromiseHookType

#[repr(C)]
pub enum PromiseHookType {
    Init,
    Resolve,
    Before,
    After,
}

PromiseHook with type Init is called when a new promise is created. When a new promise is created as part of the chain in the case of Promise.then or in the intermediate promises created by Promise.{race, all}/AsyncFunctionAwait, we pass the parent promise otherwise we pass undefined.

PromiseHook with type Resolve is called at the beginning of resolve or reject function defined by CreateResolvingFunctions.

PromiseHook with type Before is called at the beginning of the PromiseReactionJob.

PromiseHook with type After is called right at the end of the PromiseReactionJob.

impl Clone for PromiseHookType

fn clone(&self) -> PromiseHookType

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PromiseHookType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl PartialEq<PromiseHookType> for PromiseHookType

fn eq(&self, other: &PromiseHookType) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
