Enum State

pub enum State {
    CheckingForUpdates(CheckingForUpdatesData),
    ErrorCheckingForUpdate(ErrorCheckingForUpdateData),
    NoUpdateAvailable(NoUpdateAvailableData),
    InstallationDeferredByPolicy(InstallationDeferredData),
    InstallingUpdate(InstallingData),
    WaitingForReboot(InstallingData),

}

The set of states that a [Monitor] can receive during an update check.

An update check ends when it enters a terminal state, denoted below as the states on the right-hand side of the diagram with no arrows leading out of them.

Variants

CheckingForUpdates(CheckingForUpdatesData)

The Manager is currently checking for an update.

Next states:

• installing_update update is available and allowed by policy
• error_checking_for_update on error
• update_deferred_by_policy update is available but deferred by policy

ErrorCheckingForUpdate(ErrorCheckingForUpdateData)

The Manager encountered an error while checking for the existence of a a new update.

This is a terminal state

NoUpdateAvailable(NoUpdateAvailableData)

There is not update available at this time.

This is a terminal state

InstallationDeferredByPolicy(InstallationDeferredData)

The Manager has found an available update but is not acting on it at this time due to policy restrictions.

This is a terminal state

InstallingUpdate(InstallingData)

The Manager is installing the available update.

Next states:

• waiting_for_reboot on success
• installation_error on error

WaitingForReboot(InstallingData)

The update has been installed, and the device is waiting to be rebooted.

Next states:

• (none, the device reboots)

This is a terminal state

InstallationError(InstallationErrorData)

The Manager encountered an update in the installation of the update.

This is a terminal state

Implementations

impl State

pub fn ordinal(&self) -> u64

pub fn is_unknown(&self) -> bool

👎Deprecated: Strict unions should not use is_unknown

Trait Implementations

impl Clone for State

fn clone(&self) -> State

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for State

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

Formats the value using the given formatter.

impl<D: ResourceDialect> Decode<State, D> for State

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<State, D> for &State

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 PartialEq for State

fn eq(&self, other: &State) -> 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 TypeMarker for State

type Owned = State

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 State

type Borrowed<'a> = &'a State

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.

impl Persistable for State

impl StructuralPartialEq for State
