#[repr(transparent)]
pub struct SyncCell<T: ?Sized> { /* private fields */ }
Expand description

See Exclusive for stdlib’s upcoming implementation, which should replace this one entirely.

Provides a wrapper that allows making any type unconditionally Sync by only providing mutable access.

Implementations§

source§

impl<T: Sized> SyncCell<T>

source

pub fn new(inner: T) -> Self

Construct a new instance of a SyncCell from the given value.

source

pub fn to_inner(_: Self) -> T

Deconstruct this SyncCell into its inner value.

source§

impl<T: ?Sized> SyncCell<T>

source

pub fn get(&mut self) -> &mut T

Get a reference to this SyncCell’s inner value.

source

pub fn read(&self) -> &Twhere T: Sync,

For types that implement Sync, get shared access to this SyncCell’s inner value.

source

pub fn from_mut(r: &mut T) -> &mut SyncCell<T>

Build a mutable reference to a SyncCell from a mutable reference to its inner value, to skip constructing with new().
