Enum r3_core::kernel::TryLockMutexError

#[repr(i8)]
pub enum TryLockMutexError {
    NoAccess,
    BadContext,
    Timeout,
    WouldDeadlock,
    BadParam,
    Abandoned,
}

Error type for Mutex::try_lock.

See ResultCode for all result codes and generic descriptions.

Variants

NoAccess

Invalid object access.

BadContext

CPU Lock is active, or the current context is not a task context.

Timeout

WouldDeadlock

The current task already owns the mutex.

BadParam

The mutex was created with the protocol attribute having the value Ceiling and the current task’s priority is higher than the mutex’s priority ceiling.

Abandoned

The previous owning task exited while holding the mutex lock. The current task shall hold the mutex lock, but is up to make the state consistent.

Trait Implementations

impl Clone for TryLockMutexError

fn clone(&self) -> TryLockMutexError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TryLockMutexError

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

Formats the value using the given formatter.

impl From<TryLockMutexError> for ResultCode

fn from(x: TryLockMutexError) -> Self

Converts to this type from the input type.

impl Hash for TryLockMutexError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for TryLockMutexError

fn cmp(&self, other: &TryLockMutexError) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<TryLockMutexError> for TryLockMutexError

fn eq(&self, other: &TryLockMutexError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<TryLockMutexError> for TryLockMutexError

fn partial_cmp(&self, other: &TryLockMutexError) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
