Struct Decoder

pub struct Decoder { /* private fields */ }

Decoder for metrics received from an Encoder

Implements MetricsSource to export the decoded metrics to OpenMetrics.

Implementations

impl Decoder

pub fn import(&mut self, update: Update)

Imports a metric update.

Updates the decoder’s schema (if provided) and values with the given update.

pub fn import_bytes(&mut self, data: &[u8]) -> Result<(), Error>

Imports a metric update from serialized bytes.

Deserializes the bytes using postcard and imports the resulting update.

pub fn iter(&self) -> DecoderIter<'_>

Creates an iterator over the decoded metric items.

Returns an iterator that yields Item instances combining schema and value data.

Trait Implementations

impl Debug for Decoder

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

Formats the value using the given formatter.

impl Default for Decoder

fn default() -> Decoder

Returns the “default value” for a type.

impl MetricsSource for Decoder

fn encode_openmetrics(&self, writer: &mut impl Write) -> Result<(), Error>

Encodes all metrics into a string in the OpenMetrics text format.

fn encode_openmetrics_to_string(&self) -> Result<String, Error>

Encodes the metrics in the OpenMetrics text format into a newly allocated string.
