Enum LockError

pub enum LockError {
    BadContext(MaybeKind),
    NotSupported(MaybeKind),
    BadId(MaybeKind),
    AccessDenied(MaybeKind),
    Released(MaybeKind),
    TerminateRequest(MaybeKind),
    Deleted(MaybeKind),
    BadParam(MaybeKind),
    Deadlock(MaybeKind),
}

Available on crate feature unstable only.

Error type for MutexRef::lock.

This type is an error kind type.

Variants

BadContext(MaybeKind)

Requires: cfg(not(feature = "none"))

NotSupported(MaybeKind)

The task is a restricted task.

Requires: cfg(all(not(feature = "none"), feature = "rstr_task"))

BadId(MaybeKind)

Requires: cfg(not(feature = "none"))

AccessDenied(MaybeKind)

Requires: cfg(any())

Released(MaybeKind)

Requires: cfg(not(feature = "none"))

TerminateRequest(MaybeKind)

Requires: cfg(not(feature = "none"))

Deleted(MaybeKind)

Requires: cfg(all(not(feature = "none"), feature = "dcre"))

BadParam(MaybeKind)

The calling task’s priority is higher than the mutex’s priority ceiling.

Rationale

The EINVAL error of pthread_mutex_lock. This error kind is designed to accomodate any precondition violations that may occur in yet-to-be-seen kernels to be supported.

Requires: cfg(not(feature = "none"))

Deadlock(MaybeKind)

The calling task already owns the mutex.

Requires: cfg(not(feature = "none"))

Trait Implementations

impl Clone for LockError

fn clone(&self) -> LockError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LockError

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

Formats the value using the given formatter.

impl ErrorKind for LockError

fn from_error_code(code: ErrorCode) -> Option<Self>

Categorize the specified error code.

impl PartialEq for LockError

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

Tests for self and other values to be equal, and is used by ==.

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

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