# Enum Otlp File Format

> On-disk encoding used by `OtlpFileSpanExporter`.

Generated from `cargo doc --no-deps -p nemo-relay -p nemo-relay-adaptive -p nemo-relay-pii-redaction -p nemo-relay-ffi -p nemo-relay-types -p nemo-relay-plugin -p nemo-relay-worker-proto -p nemo-relay-worker`.

```rust
pub enum OtlpFileFormat {
    JsonLines,
    Proto,
}
```

On-disk encoding used by [`OtlpFileSpanExporter`](/reference/api/rust-library-reference/nemo-relay/observability/otel_file/struct-otlpfilespanexporter).

## Variants

### `JsonLines`

<pre />

One OTLP/JSON-encoded `ExportTraceServiceRequest` per line: the serialization the OpenTelemetry file-exporter specification describes, and the default for that reason.

### `Proto`

<pre />

Length-delimited OTLP protobuf: a big-endian `u32` byte count followed by that many bytes of encoded `ExportTraceServiceRequest`.

## Implementations

### `impl OtlpFileFormat`

<pre />

#### `extension`

<pre />
