Reasons why a device last rebooted.

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<D: ResourceDialect> Decode<RebootReason, D> for RebootReason

fn new_empty() -> Self

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_, D>, offset: usize, _depth: Depth, ) -> Result<()>

Decodes an object of type T from the decoder’s buffers into self.

impl<D: ResourceDialect> Encode<RebootReason, D> for RebootReason

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, offset: usize, _depth: Depth, ) -> Result<()>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

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 Ord for RebootReason

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for RebootReason

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

impl PartialOrd 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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TypeMarker for RebootReason

type Owned = RebootReason

The owned Rust type which this FIDL type decodes into.

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 alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for RebootReason

type Borrowed<'a> = RebootReason

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow(value: &<Self as TypeMarker>::Owned) -> Self::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.
