Why the system is shutting down.

Variants

UserRequest

The end user of the device initiated the shutdown.

DO NOT USE for any code path not directly related to an end user explicit shutdown action. Use DEVELOPER_REQUEST below instead.

DeveloperRequest

The developer initiated the shutdown, typically via a shell command or similar interface, including within an automated test.

SystemUpdate

A new system update has been downloaded.

RetrySystemUpdate

Applying the system update has failed.

HighTemperature

The device has crossed the high temperature threshold.

FactoryDataReset

The device is about to perform an FDR.

SessionFailure

Sessionmgr has failed.

CriticalComponentFailure

A critical system component has failed.

ZbiSwap

A boot partition change was effected.

OutOfMemory

The system hit a critical low threshold of available memory.

NetstackMigration

The Netstack component is changing versions.

AndroidUnexpectedReason

An Android-initiated shutdown reason that Starnix doesn’t recognize.

AndroidRescueParty

Android called for the “RescueParty”.

AndroidCriticalProcessFailure

A critical Android process failed.

Implementations

impl ShutdownReason

pub fn from_primitive(prim: u32) -> Option<ShutdownReason>

pub fn from_primitive_allow_unknown(prim: u32) -> ShutdownReason

pub fn unknown() -> ShutdownReason

pub const fn into_primitive(self) -> u32

pub fn is_unknown(&self) -> bool

Trait Implementations

impl Clone for ShutdownReason

fn clone(&self) -> ShutdownReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShutdownReason

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

Formats the value using the given formatter.

impl<D> Decode<ShutdownReason, D> for ShutdownReason

where D: ResourceDialect,

fn new_empty() -> ShutdownReason

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<(), Error>

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

impl<D> Encode<ShutdownReason, D> for ShutdownReason

where D: ResourceDialect,

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

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

impl Hash for ShutdownReason

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 ShutdownReason

fn cmp(&self, other: &ShutdownReason) -> 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 ShutdownReason

fn eq(&self, other: &ShutdownReason) -> 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 ShutdownReason

fn partial_cmp(&self, other: &ShutdownReason) -> 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 ShutdownReason

type Owned = ShutdownReason

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 ShutdownReason

type Borrowed<'a> = ShutdownReason

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: &<ShutdownReason as TypeMarker>::Owned, ) -> <ShutdownReason as ValueTypeMarker>::Borrowed<'_>

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