Enum CondvarWaitError 

pub enum CondvarWaitError {
    TimedOut,
    Invalid,
    Permission,
    OwnerDead,
    NotRecoverable,
    Other(i32),
}

The error type returned from a wait or a timed wait on a condvar.

The variant descriptions and Display impls for this error type are based on info from the POSIX man pages. The semantics, however, are platform-dependent. Consult the man pages of your operating system for more relevant error descriptions.

Variants

TimedOut

The deadline of a timed wait passed before the condvar was notified. The timed waits here report that outcome as WaitOutcome::TimedOut, so this variant only shows up when a raw errno is converted by hand.

Invalid

This error can occur for several reasons:

• The deadline’s nanosecond value was out of range. This is the only case POSIX requires reporting.
• The condvar or the mutex does not refer to an initialised object, or concurrent waits on the same condvar were passed guards belonging to different mutexes. POSIX recommends rather than requires reporting these, so whether they are detected is up to the platform.

Permission

The mutex is error-checking or robust and the calling thread does not own it. The waits in this crate take a guard, which is proof of ownership, so this variant only shows up when a raw errno is converted by hand.

OwnerDead

The mutex is robust and its previous owner terminated while holding the lock. The wait nevertheless returned with the mutex locked, so the guard is still good: repair the data it protects and call mark_consistent on it, or every later lock will fail with NotRecoverable.

NotRecoverable

The mutex is robust, its previous owner died holding the lock, and nobody marked the data consistent afterwards.

Other(i32)

None of the above. Contains the libc error code.
