Reasons why a device last rebooted.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unknown

The client will get this value if the server is sending a new enum value that the client was not compiled with.

Cold

The device booted from a cold state.

This is most likely the result of an extended period of time without power or a device booting with Fuchsia for the first time.

BriefPowerLoss

The device rebooted due to a brief loss of power.

On some hardware this could be the result of a user disconnecting, then reconnecting their device’s power supply in rapid succession.

Brownout

The device rebooted because its voltage dipped below an allowable level without going to 0.

KernelPanic

SystemOutOfMemory

HardwareWatchdogTimeout

SoftwareWatchdogTimeout

RootJobTermination

The device rebooted because the userspace root job was terminated, most likely because one of its critical processes crashed.

UserRequest

The device rebooted because a user of the device initiated the reboot. A user can be a human or a program that interacts with the device on behalf of a human, such as SL4F or RCS.

SystemUpdate

The device rebooted because of an OTA.

RetrySystemUpdate

The device rebooted because applying the OTA failed and we want to retry.

HighTemperature

The device rebooted because it was determined to be too hot.

SessionFailure

The device rebooted because of an issue with a session or because the session manager was unable to recover from an error.

SysmgrFailure

The device rebooted because the system manager (sysmgr) was unable to recover from an error.

FactoryDataReset

The device rebooted following a data reset to factory defaults. See [fuchsia.recovery.FactoryReset].

CriticalComponentFailure

The device rebooted because a critical component managed by sysmgr has failed.

ZbiSwap

The device rebooted to apply the swap of Zircon boot images.

Implementations

impl RebootReason

pub fn from_primitive(prim: u16) -> Option<Self>

pub fn from_primitive_allow_unknown(prim: u16) -> Self

pub fn unknown() -> Self

pub const fn into_primitive(self) -> u16

pub fn is_unknown(&self) -> bool

Trait Implementations

impl Clone for RebootReason

fn clone(&self) -> RebootReason

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RebootReason

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

Formats the value using the given formatter.

impl Decodable for RebootReason

fn new_empty() -> Self

Creates a new value of this type with an “empty” representation.

fn decode( &mut self, decoder: &mut Decoder<'_>, offset: usize ) -> Result<(), Error>

Decodes an object of this type from the decoder’s buffers into self. Callers must ensure that offset is a multiple of Layout::inline_align, and that decoder.buf has room for reading Layout::inline_size bytes at offset.

impl Encodable for RebootReason

fn encode( &mut self, encoder: &mut Encoder<'_, '_>, offset: usize, recursion_depth: usize ) -> Result<(), Error>

Encode the object into the buffer. Any handles stored in the object are swapped for Handle::INVALID. Callers must ensure that offset is a multiple of Layout::inline_align, and that encoder.buf has room for writing Layout::inline_size bytes at offset.

impl Hash for RebootReason

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 Layout for RebootReason

fn inline_align(context: &Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(context: &Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for the type’s alignment. Must be a multiple of inline_align.

fn supports_simple_copy() -> boolwhere Self: Sized,

Returns true iff the type can be encoded or decoded via simple copy.

impl Ord for RebootReason

fn cmp(&self, other: &RebootReason) -> 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<RebootReason> for RebootReason

fn eq(&self, other: &RebootReason) -> 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<RebootReason> for RebootReason

fn partial_cmp(&self, other: &RebootReason) -> 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.
