Enum MetricEventPayload

pub enum MetricEventPayload {
    Count(u64),
    IntegerValue(i64),
    Histogram(Vec<HistogramBucket>),
    StringValue(String),
    // some variants omitted
}

The variadic part of a MetricEvent.

Variants

Count(u64)

The number of times the event has occurred, see LogOccurrence().

IntegerValue(i64)

The integer measured, see LogInteger().

Histogram(Vec<HistogramBucket>)

The collection of approximate integer measurements, see LogIntegerHistogram().

StringValue(String)

The string to log, see LogString().

Implementations

impl MetricEventPayload

pub fn unknown_variant_for_testing() -> MetricEventPayload

pub fn is_unknown(&self) -> bool

Trait Implementations

impl Clone for MetricEventPayload

fn clone(&self) -> MetricEventPayload

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MetricEventPayload

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

Formats the value using the given formatter.

impl<D> Decode<MetricEventPayload, D> for MetricEventPayload

where D: ResourceDialect,

fn new_empty() -> MetricEventPayload

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<MetricEventPayload, D> for &MetricEventPayload

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 PartialEq for MetricEventPayload

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

type Owned = MetricEventPayload

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 MetricEventPayload

type Borrowed<'a> = &'a MetricEventPayload

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

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