Struct DropNotifyWatchSender 

pub struct DropNotifyWatchSender<T: DropNotifyEofSignallable>(/* private fields */);

Wrapper for postage::watch::Sender that sends DropNotifyEof::eof() when dropped

Derefs to the inner Sender.

Ideally this would be behaviour promised by upstream, or something See https://github.com/austinjones/postage-rs/issues/57.

Implementations

impl<T: DropNotifyEofSignallable> DropNotifyWatchSender<T>

pub fn new(inner: Sender<T>) -> Self

Arrange to send T::Default when inner is dropped

pub fn into_inner(self) -> Sender<T>

Unwrap the inner sender, defusing the drop notification

Methods from Deref<Target = Sender<T>>

pub fn borrow_mut<'s>(&'s mut self) -> RefMut<'s, T>

Mutably borrows the contained value, blocking the channel while the borrow is held.

After the borrow is released, receivers will be notified of a new value.

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

Creates a new Receiver that listens to this channel.

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

Immutably borrows the contained value, blocking the channel while the borrow is held.

Trait Implementations

impl<T: Debug + DropNotifyEofSignallable> Debug for DropNotifyWatchSender<T>

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

Formats the value using the given formatter.

impl<T: DropNotifyEofSignallable> Deref for DropNotifyWatchSender<T>

type Target = Sender<T>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T: DropNotifyEofSignallable> DerefMut for DropNotifyWatchSender<T>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<T: DropNotifyEofSignallable> Drop for DropNotifyWatchSender<T>

fn drop(&mut self)

Executes the destructor for this type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
