Struct mesh::OneshotReceiver

pub struct OneshotReceiver<T>(/* private fields */);

The receiving half of a channel returned by oneshot.

A value is received by polling or awaiting the channel.

Implementations

impl<T> OneshotReceiver<T>

where T: MeshField,

pub fn upcast<U>(self) -> OneshotReceiver<U>

where U: MeshField, OneshotReceiver<T>: Upcast<OneshotReceiver<U>>,

Upcasts this receiver to one that can receive values whose encoding is a superset of T’s.

pub fn force_downcast<U>(self) -> OneshotReceiver<U>

where U: MeshField, OneshotReceiver<U>: Upcast<OneshotReceiver<T>>,

Downcasts this receiver to one that can receive values whose encoding is a subset of T’s.

Although this is memory safe, it can cause decoding failures if the associated sender sends values that don’t decode to U.

Trait Implementations

impl<T> Debug for OneshotReceiver<T>

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

Formats the value using the given formatter.

impl<T> DefaultEncoding for OneshotReceiver<T>

where T: MeshField,

type Encoding = TableEncoder

The encoding to use for the serialization.

impl<T> From<OneshotReceiver<T>> for Port

where T: MeshField,

Converts to this type from the input type.

impl<T> From<Port> for OneshotReceiver<T>

where T: MeshField,

Converts to this type from the input type.

impl<T> Future for OneshotReceiver<T>

where T: 'static + Send,
