Struct Handle

pub struct Handle<T: ?Sized> { /* private fields */ }

Reference-counted async RwLock

Implementations

impl<T> Handle<T>

pub fn new(value: T) -> Self

Creates a new handle wrapping value

pub async fn read(&self) -> RwLockReadGuard<'_, T>

Lock the contained value for reading

pub async fn write(&self) -> RwLockWriteGuard<'_, T>

Lock the contained value for writing

pub fn try_unwrap(self) -> Result<T, Self>

pub fn ptr_eq(this: &Self, other: &Self) -> bool

Returns true if the two Handles point to the same allocation (in a vein similar to Arc::ptr_eq).

impl<T> Handle<T>

where T: Clone,

pub async fn cloned(&self) -> Self

Returns a new Handle with a clone of the value within
