Enum boa_engine::builtins::promise::PromiseState
source · pub enum PromiseState {
Pending,
Fulfilled(JsValue),
Rejected(JsValue),
}
Expand description
The current state of a Promise
.
Variants§
Pending
The promise hasn’t been resolved.
Fulfilled(JsValue)
The promise was fulfilled with a success value.
Rejected(JsValue)
The promise was rejected with a failure reason.
Implementations§
source§impl PromiseState
impl PromiseState
sourcepub const fn as_fulfilled(&self) -> Option<&JsValue>
pub const fn as_fulfilled(&self) -> Option<&JsValue>
Gets the inner JsValue
of a fulfilled promise state, or returns None
if
the state is not Fulfilled
.
sourcepub const fn as_rejected(&self) -> Option<&JsValue>
pub const fn as_rejected(&self) -> Option<&JsValue>
Gets the inner JsValue
of a rejected promise state, or returns None
if
the state is not Rejected
.
