pub struct Sender<T>(/* private fields */);
Expand description
The transmitting end of a channel.
Use bounded
or rendezvous
to create a channel. You can also convert an UnboundSender
into this one.
Implementations§
source§impl<T> Sender<T>
impl<T> Sender<T>
sourcepub async fn send(&self, msg: T) -> Result<(), SendError<T>>
pub async fn send(&self, msg: T) -> Result<(), SendError<T>>
Send a value into the channel.
Waits until there is space in the channel buffer.
Returns an error if all receivers have been dropped.
sourcepub async fn send_deadline(
&self,
msg: T,
deadline: impl Into<Deadline>,
) -> Result<(), SendTimeoutError<Option<T>>>
pub async fn send_deadline( &self, msg: T, deadline: impl Into<Deadline>, ) -> Result<(), SendTimeoutError<Option<T>>>
Send a value into the channel.
Waits until there is space in the channel buffer or the deadline
is reached.
Returns an error if all receivers have been dropped or the deadline
is reached. The msg
is lost in case of timeout.
sourcepub fn is_disconnected(&self) -> bool
pub fn is_disconnected(&self) -> bool
Returns true
if all receivers for this channel have been dropped.
sourcepub fn is_empty(&self) -> bool
pub fn is_empty(&self) -> bool
Returns true
if the channel is empty.
Note: rendezvous
channels are always empty.
sourcepub fn is_full(&self) -> bool
pub fn is_full(&self) -> bool
Returns true
if the channel is full.
Note: rendezvous
channels are always full and unbounded
channels are never full.
