Struct ExceptionFree

pub struct ExceptionFree<'cs> { /* private fields */ }

A token proving that exceptions are currently masked.

Note that synchronous exceptions cannot be masked and so may still occur.

Implementations

impl<'cs> ExceptionFree<'cs>

pub unsafe fn new() -> Self

Constructs a new instance of ExceptionFree, promising that exceptions will remain masked for at least its lifetime.

This usually should not be called directly; instead use exception_free.

Safety

ExceptionFree must only be constructed while exceptions are masked, and they must not be unmasked until after it is dropped.
