Enum HealthAlert 

pub enum HealthAlert {
    SelfFault(HealthCheckResponse),
    UpstreamNeighborFault(HealthCheckResponse),
    DownstreamNeighborFault(HealthCheckResponse),
    // some variants omitted
}

Payload of a proactive health alert emitted by a driver via OnHealthAlert. “Upstream” is what the driver depends on (parents: buses, clocks, power domains, composite parents). “Downstream” is what depends on the driver (children / consumers).

Variants

SelfFault(HealthCheckResponse)

The driver detected an internal hardware or software fault, or recovered from a previously reported fault (when conditions is empty). Edge-triggered: send when the driver’s overall status worsens (OK->DEGRADED, DEGRADED->UNHEALTHY) and again with empty conditions when it recovers; never per occurrence of an already-reported condition.

UpstreamNeighborFault(HealthCheckResponse)

The driver cannot make progress because an upstream dependency (parent/bus/clock/power/register provider) is unresponsive or invalid.

DownstreamNeighborFault(HealthCheckResponse)

The driver cannot make progress because a downstream consumer (child/client) is wedged or failing to drain queues/buffers.

Implementations

impl HealthAlert

pub fn ordinal(&self) -> u64

pub fn unknown_variant_for_testing() -> Self

pub fn is_unknown(&self) -> bool

Trait Implementations

impl Clone for HealthAlert

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HealthAlert

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

Formats the value using the given formatter.

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

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<HealthAlert, D> for &HealthAlert

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 HealthAlert

fn eq(&self, other: &Self) -> bool

Equality operator ==.

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

Inequality operator !=.

impl Persistable for HealthAlert

impl TypeMarker for HealthAlert

type Owned = HealthAlert

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 HealthAlert

type Borrowed<'a> = &'a HealthAlert

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.
