Struct Sender 

pub struct Sender<T> { /* private fields */ }

Producer side. Only one sender is supported per channel today; the API matches tokio’s single-producer semantics.

Implementations

impl<T> Sender<T>

pub fn send(&self, value: T) -> Result<(), SendError<T>>

Replace the current value, bumping the version and waking every receiver parked in changed(). Returns the value back via SendError if every receiver has been dropped.

pub fn is_closed(&self) -> bool

Returns true once every receiver has been dropped.

pub fn subscribe(&self) -> Receiver<T>

Build a fresh receiver subscribed at the current version. The new receiver’s first changed() call resolves only after a future send.

pub fn borrow(&self) -> Ref<'_, T>

Read-only borrow of the current value. Does NOT update any per-receiver seen-state because the sender has no notion of per-receiver state.

Trait Implementations

impl<T> Drop for Sender<T>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
