Struct MutHandle

pub struct MutHandle<'a, T> {
    pub value: &'a UnsafeCell<MaybeUninit<T>>,
    /* private fields */
}

Provides a mut-handle on the optional.

Fields

value: &'a UnsafeCell<MaybeUninit<T>>

Provides direct access to the cell holding the data of the optional.

Implementations

impl<'a, T> MutHandle<'a, T>

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

Creates a &mut T reference to the underlying value of the optional.

Safety

This operation might lead to undefined behavior:

• if we use it while other threads are accessing the data, or
• if the optional is_none when we access the value.

Trait Implementations

impl<T> Drop for MutHandle<'_, T>

fn drop(&mut self)

Executes the destructor for this type.
