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().

Similar to MutexGuard but specifically for ISR context. Automatically unlocks the mutex when dropped using ISR-safe unlock.

Examples

// In ISR context:
if let Ok(mut guard) = mutex.lock_from_isr() {
    *guard = new_value;
}  // Automatically unlocked with ISR-safe method

Trait Implementations

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

Provides immutable access to the protected data from ISR context.

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

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

Provides mutable access to the protected data from ISR context.

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

Mutably dereferences the value.

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

Automatically unlocks the mutex using ISR-safe unlock when the guard goes out of scope.

fn drop(&mut self)

Executes the destructor for this type.

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

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

where T: Clone,

Updates the protected value from ISR context.

Note

This requires T to implement Clone to copy the value.

Examples

// In ISR context:
if let Ok(mut guard) = mutex.lock_from_isr() {
    guard.update(&new_value);
}
