Struct ThreadCell 

pub struct ThreadCell<T: 'static> { /* private fields */ }

A cell that holds a value bound to a single thread. Thus T can be non-Send and/or non-Sync, but ThreadCell<T> is always Send/Sync. Access is provided through message passing, so no internal locking is used. But a lock-like ThreadCellSession can be acquired to gain exclusive access to the underlying resource while held.

Implementations

impl<T: Send> ThreadCell<T>

pub fn new(resource: T) -> Self

Creates new

impl<T> ThreadCell<T>

pub fn new_with<F: FnOnce() -> T + Send + 'static>(resource_fn: F) -> Self

Creates a new when T is not Send but a function to create T is

pub fn run_blocking<F, R>(&self, f: F) -> R

where F: FnOnce(&mut T) -> R + Send + 'static, R: Send + 'static,

pub fn session_blocking(&self) -> ThreadCellSession<T>

impl<T: Send> ThreadCell<T>

pub fn set_blocking(&self, new_value: T)

Set the resource in a blocking manner

pub fn replace_blocking(&self, new_value: T) -> T

Set the resource in a blocking manner, returning the old value

impl<T: Send + Default> ThreadCell<T>

pub fn take_blocking(&self) -> T

impl<T: Send + Clone> ThreadCell<T>

pub fn get_blocking(&self) -> T

Get a clone of the resource in a blocking manner

Trait Implementations

impl<T: 'static> Clone for ThreadCell<T>

fn clone(&self) -> Self
