Struct MutexGuardFromIsr 

pub struct MutexGuardFromIsr<'a, T: ?Sized + 'a> { /* private fields */ }

Mutex types and guards for mutual exclusion. RAII guard returned by Mutex::lock_from_isr/Mutex::lock_from_isr_explicit. Unlocks the mutex (via the non-blocking _from_isr path) when dropped; derefs to &T/&mut T in the meantime.

Trait Implementations

impl<'a, T: ?Sized> Deref for MutexGuardFromIsr<'a, T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<'a, T: ?Sized> DerefMut for MutexGuardFromIsr<'a, T>

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

Mutably dereferences the value.

impl<'a, T: ?Sized> Drop for MutexGuardFromIsr<'a, T>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl<'a, T: ?Sized> MutexGuard<'a, T> for MutexGuardFromIsr<'a, T>

fn update(&mut self, t: &T)

where T: Clone,

See MutexGuard::update; behaves identically here.

Examples

use osal_rs::os::*;

let mutex = Mutex::new(0);
let mut guard = mutex.lock_from_isr().unwrap();
guard.update(&7);
assert_eq!(*guard, 7);
