Struct CompositeExporter 

pub struct CompositeExporter { /* private fields */ }

Fan-out exporter for logs, billing, analytics, and audit sinks.

Exporters run in registration order. If one fails, a later retry starts from the first exporter. Provider implementations must therefore honor the stable aggregate identifiers, as required by BatchExporter.

Implementations

impl CompositeExporter

pub const fn new() -> CompositeExporter

Construct an empty fan-out exporter.

pub fn with_exporter( self, exporter: Arc<dyn BatchExporter>, ) -> CompositeExporter

Append an exporter to the fan-out sequence.

pub fn len(&self) -> usize

Number of configured exporters.

pub fn is_empty(&self) -> bool

Whether no exporters are configured.

fn export<'a>( &'a self, batch: &'a [AggregatedUsage], ) -> Pin<Box<dyn Future<Output = Result<(), ExportError>> + Send + 'a>>

Export every aggregate in batch.

impl Debug for CompositeExporter

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

Formats the value using the given formatter.

impl Default for CompositeExporter

fn default() -> CompositeExporter

Returns the “default value” for a type.
