OffStackRef

openhcl_boot::single_threaded

Struct OffStackRef 

Source 
pub struct OffStackRef<'a, T>(&'a mut T, BorrowRef<'a>);
Expand description

A reference returned by off_stack.

Tuple Fields§

§0: &'a mut T§1: BorrowRef<'a>

Implementations§

Source§

impl<'a, T> OffStackRef<'a, T>

Source

pub fn leak(this: Self) -> &'a mut T

Leaks the borrow, returning the reference.

This will lead to a panic if there is an attempt to borrow the value again (e.g., if the function invoking the off_stack macro is called again).

Trait Implementations§

Source§

impl<T> Deref for OffStackRef<'_, T>

Source§

type Target = T

Source§

fn deref(&self) -> &T

Dereferences the value.
Source§

impl<T> DerefMut for OffStackRef<'_, T>

Source§

fn deref_mut(&mut self) -> &mut T
