Variants

Invalid = 0

0 is reserved for “Invalid”. It will never be used by a functioning crash-logger.

Unknown = 1

“Unknown” indicates that the system does not know the reason for a recent crash. The primary use of this reason is to be something which can be left in the crashlog in case the system spontaneously reboots without a chance to gracefully finalize the log, perhaps because of something like a hardware watchdog timer.

NoCrash = 2

“No Crash” indicates that the system deliberately rebooted in an orderly fashion. No crash occurred.

Oom = 3

“OOM” indicates a crash triggered by the system because of an unrecoverable out-of-memory situation.

Panic = 4

“Panic” indicates a crash triggered by the system because of an unrecoverable kernel panic situation.

SoftwareWatchdog = 5

“Software watchdog” indicates a crash triggered by a kernel level software watchdog construct. Note that this is distinct from a hardware based WDT. If the system reboots because of a hardware watchdog, it will have no chance to record the reboot reason, and the crashlog will indicate “unknown”. The HW reboot reason may be known, but only if the bootloader reports it to us.

UserspaceRootJobTermination = 6

“Userspace root job termination” indicates a crash triggered by the system because it detected the termination of the userspace root job, most likely because one of its critical processes crashed.

Trait Implementations

impl Clone for ZirconCrashReason

fn clone(&self) -> ZirconCrashReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ZirconCrashReason

impl Debug for ZirconCrashReason

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

Formats the value using the given formatter.

impl Eq for ZirconCrashReason

impl PartialEq for ZirconCrashReason

fn eq(&self, other: &ZirconCrashReason) -> 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.
