Implementations

impl SpanExporter

pub fn new_tonic( config: ExportConfig, tonic_config: TonicConfig ) -> Result<Self, Error>

Builds a new span exporter with the given configuration.

pub fn from_tonic_channel( config: ExportConfig, tonic_config: TonicConfig, channel: Channel ) -> Result<Self, Error>

Builds a new span exporter with given tonic channel.

This allows users to bring their own custom channel like UDS. However, users MUST make sure the ExportConfig::timeout is the same as the channel’s timeout.

Trait Implementations

impl Debug for SpanExporter

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

Formats the value using the given formatter.

impl SpanExporter for SpanExporter

fn export<'life0, 'async_trait>( &'life0 mut self, batch: Vec<SpanData> ) -> Pin<Box<dyn Future<Output = ExportResult> + Send + 'async_trait>>where Self: 'async_trait, 'life0: 'async_trait,

Exports a batch of readable spans. Protocol exporters that will implement this function are typically expected to serialize and transmit the data to the destination.

fn shutdown(&mut self)

Shuts down the exporter. Called when SDK is shut down. This is an opportunity for exporter to do any cleanup required.
