Struct RawMutex 

pub struct RawMutex(/* private fields */);

Low-level recursive mutex wrapper for FreeRTOS.

This is the underlying implementation of the mutex that directly interfaces with FreeRTOS semaphore APIs. It’s recursive, meaning the same thread can lock it multiple times.

Note

Users should typically use Mutex<T> instead, which provides type-safe data protection. This type is exposed for advanced use cases.

Implementations

impl RawMutex

pub fn new() -> Result<Self>

Creates a new raw recursive mutex.

Returns

• Ok(RawMutex) - Successfully created
• Err(Error::OutOf Memory) - Failed to allocate mutex resources

Trait Implementations

impl Debug for RawMutex

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Deref for RawMutex

type Target = *const c_void

The resulting type after dereferencing.

fn deref(&self) -> &MutexHandle

Dereferences the value.

impl Display for RawMutex

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for RawMutex

fn drop(&mut self)

Executes the destructor for this type.

impl RawMutex for RawMutex

fn lock(&self) -> OsalRsBool

Locks the mutex (blocking).

fn lock_from_isr(&self) -> OsalRsBool

Locks the mutex from ISR context (non-blocking).

fn unlock(&self) -> OsalRsBool

Unlocks the mutex.

fn unlock_from_isr(&self) -> OsalRsBool

Unlocks the mutex from ISR context.

fn delete(&mut self)

Deletes the mutex and frees its resources.
