Struct Ref 

pub struct Ref<'a, T> { /* private fields */ }

Reference to borrowed value.

Holds reference will prevent it from reclamation so drop it as soon as possible.

Implementations

impl<'a, T> Ref<'a, T>

pub fn has_changed(&self) -> bool

Do we ever seen this before from last Receiver::borrow_and_update and Receiver::changed() ?

Trait Implementations

impl<T> AsRef<T> for Ref<'_, T>

fn as_ref(&self) -> &T

Converts this type into a shared reference of the (usually inferred) input type.

impl<T: Debug> Debug for Ref<'_, T>

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

Formats the value using the given formatter.

impl<T> Deref for Ref<'_, T>

type Target = T

The resulting type after dereferencing.

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

Dereferences the value.

impl<T> Drop for Ref<'_, T>

fn drop(&mut self)

Executes the destructor for this type.

impl<T> Send for Ref<'_, T>

impl<T> Sync for Ref<'_, T>
