Struct Metric 

pub struct Metric { /* private fields */ }

A simplified metric representation.

Implementations

impl Metric

pub fn context(&self) -> &MetricContext

Returns the context of the metric.

pub fn values(&self) -> &[(u64, MetricValue)]

Returns the values associated with the metric.

impl Metric

pub fn try_from_series_v1(payload: &[u8]) -> Result<Vec<Self>, GenericError>

Attempts to parse metrics from a series v1 payload.

V1 keeps a separate device JSON field rather than a device:<value> tag like the V2 protobuf encoder. To keep the post-conversion stele::Metric representation comparable between V1 and V2 payloads, this re-injects device:<value> into the tag list when the JSON device field is non-empty.

Errors

If the JSON can’t be deserialized, contains invalid data (for example, an unknown type), or has out-of-range timestamps, an error is returned.

pub fn try_from_series_v2( payload: MetricPayload, ) -> Result<Vec<Self>, GenericError>

Attempts to parse metrics from a series v2 payload.

Errors

If the metric payload contains invalid data, an error will be returned.

pub fn try_from_sketch( payload: SketchPayload, ) -> Result<Vec<Self>, GenericError>

Attempts to parse metrics from a sketch payload.

Errors

If the sketch payload contains invalid data, an error will be returned.

impl Metric

pub fn try_from_v3(payload: V3Payload) -> Result<Vec<Self>, GenericError>

Attempts to parse metrics from a v3 payload.

The v3 format uses columnar encoding with dictionary deduplication and delta encoding.

Errors

If the payload contains invalid data, an error will be returned.

Trait Implementations

impl Clone for Metric

fn clone(&self) -> Metric

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Metric

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Metric

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Metric

impl PartialEq for Metric

fn eq(&self, other: &Metric) -> 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 Serialize for Metric

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
