Struct TrustCell

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

A custom cell container that is a RefCell with thread-safety.

Implementations

impl<T> TrustCell<T>

pub fn new(val: T) -> TrustCell<T>

Create a new cell, similar to RefCell::new

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

Get an immutable reference to the inner data.

Absence of write accesses is checked at run-time.

Panics

This function will panic if there is a mutable reference to the data already in use.

pub fn try_borrow(&self) -> Result<Ref<'_, T>, InvalidBorrow>

Get an immutable reference to the inner data.

Absence of write accesses is checked at run-time. If access is not possible, an error is returned.

pub fn borrow_mut(&self) -> RefMut<'_, T>

Get a mutable reference to the inner data.

Exclusive access is checked at run-time.

Panics

This function will panic if there are any references to the data already in use.

pub fn try_borrow_mut(&self) -> Result<RefMut<'_, T>, InvalidBorrow>

Get a mutable reference to the inner data.

Exclusive access is checked at run-time. If access is not possible, an error is returned.

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

Gets exclusive access to the inner value, bypassing the Cell.

Exclusive access is checked at compile time.
