Struct Receiver 

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

Consumer side. Each receiver tracks its own seen-version, so two receivers can be at different positions in the value stream and neither blocks the other.

Implementations

impl<T> Receiver<T>

pub async fn changed(&mut self) -> Result<(), RecvError>

Park until the current value differs from this receiver’s last-seen version. Returns Err(RecvError) if the sender has been dropped and no further value can ever arrive. Does NOT update the seen-version — call borrow_and_update after to acknowledge.

pub fn has_changed(&self) -> Result<bool, RecvError>

Non-blocking check: has a new value arrived since the last borrow_and_update?

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

Read-only borrow of the current value without updating seen-state. A follow-up changed() call will still return Ok(()) if the version changed before this borrow.

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

Read the current value and mark it as seen so the next changed() call only resolves on a subsequent send.

Trait Implementations

impl<T> Clone for Receiver<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Drop for Receiver<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.
