Enum itron_asp3::mutex::UnlockError

pub enum UnlockError {
    BadContext(MaybeKind),
    BadId(MaybeKind),
    AccessDenied(MaybeKind),
    BadSequence(MaybeKind),
}

This is supported on crate feature unstable only.

Error type for MutexRef::unlock.

This type is an error kind type.

The mutex is not the lastly-locked mutex currently owned by the calling task (TOPPERS third-generation kernels, E_OBJ). The mutex is not currently owned by the calling task (μITRON 4.0 and μT-Kernel, E_ILUSE).

Rationale

The name was inspired by the FTP and SMTP error 503 (bad sequence of commands) and SOLID SOLID_ERR_BADSEQUENCE. A mutex is intended to be used in a specific sequence (lock followed by unlock). The TOPPERS third-generation kernels impose a more stringent requirement on the sequence: mutexes must be unlocked in a lock-reverse order.

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