Enum FailedRequest 

pub enum FailedRequest {
    Traces(ExportTraceServiceRequest),
    Metrics(ExportMetricsServiceRequest),
    Logs(ExportLogsServiceRequest),
}

The original OTLP request that failed to export.

This enum contains the exact protobuf payload that was meant to be sent to the collector. You can serialise it with to_protobuf() and send it via any transport mechanism.

Variants

Traces(ExportTraceServiceRequest)

A traces export request.

Metrics(ExportMetricsServiceRequest)

A metrics export request.

Logs(ExportLogsServiceRequest)

A logs export request.

Implementations

impl FailedRequest

pub fn to_protobuf(&self) -> Vec<u8>

Serialises the request to protobuf bytes.

This is the canonical wire format expected by OTLP collectors. You can send these bytes to any collector endpoint using your preferred transport (HTTP, gRPC, file, queue, etc.).

Example

let bytes = failure.request.to_protobuf();
s3_client.put_object(bucket, key, bytes).await?;

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

Serialises the request to JSON.

OTLP/JSON is less compact than protobuf but useful for debugging and systems that prefer JSON transport.

Errors

Returns an error if JSON serialisation fails.

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

Serialises the request to pretty-printed JSON.

Useful for debugging and human-readable output.

pub fn encoded_len(&self) -> usize

Returns the estimated serialised size in bytes.

Useful for implementing size-based filtering or batching logic in fallback handlers.

pub fn signal_type(&self) -> &'static str

Returns the signal type as a string.

Useful for logging, metrics, and routing decisions.

pub fn otlp_path(&self) -> &'static str

Returns the OTLP HTTP path for this signal type.

Useful when forwarding to an alternative collector.

pub fn item_count(&self) -> usize

Returns the number of items in the request.

For traces, this is the number of spans. For metrics, this is the number of data points. For logs, this is the number of log records.

Trait Implementations

impl Clone for FailedRequest

fn clone(&self) -> FailedRequest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FailedRequest

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

Formats the value using the given formatter.
