Struct ExceptionLock

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

Allows access to the given value only while exceptions are masked, allowing it to be shared between exception contexts on a given core.

Implementations

impl<T> ExceptionLock<T>

pub const fn new(value: T) -> Self

Creates a new ExceptionLock containing the given value.

pub fn borrow<'cs>(&'cs self, _: ExceptionFree<'cs>) -> &'cs T

Gets a unique reference to the contents of the cell, given a token proving that exceptions are currently masked.

impl<T> ExceptionLock<RefCell<T>>

pub fn borrow_mut<'cs>(&'cs self, token: ExceptionFree<'cs>) -> RefMut<'cs, T>

Gets a unique reference to the contents of the RefCell, given a token proving that exceptions are currently masked.

pub fn as_ptr(&self) -> *mut T

Returns a raw pointer to the contents of the cell.

This must not be dereferenced while any RefMut to the same cell exists.
