Struct TaskValueSource 

Source
pub struct TaskValueSource { /* private fields */ }
Expand description

The producer side of a TaskValue that is not bound to a future: the equivalent of a task completion source.

Implementations§

Source§

impl TaskValueSource

Source

pub fn new() -> Self

Source

pub fn task(&self) -> TaskValue

The task completed by this source.

Source

pub fn set_result<T: PropertyValue>(&self, value: T)

Completes the task with value. Panics if the task has already finished.

Source

pub fn set_untyped_result(&self, value: Option<BoxedValue>)

Completes the task with an untyped value. Panics if the task has already finished.

Source

pub fn set_exception(&self, error: BindingError)

Fails the task with error. Panics if the task has already finished.

Source

pub fn try_set_untyped_result(&self, value: Option<BoxedValue>) -> bool

Completes the task with an untyped value unless it has already finished.

Source

pub fn try_set_exception(&self, error: BindingError) -> bool

Fails the task with error unless it has already finished.
