# Struct Otlp File Span Exporter

> Writes exported spans to a local file as OTLP.

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 struct OtlpFileSpanExporter { /* private fields */ }
```

Writes exported spans to a local file as OTLP.

Every export is written, flushed and synced before it returns, so a batch the SDK reports as delivered has reached the disk and a run that dies mid-stream leaves a readable prefix.

## Implementations

### `impl OtlpFileSpanExporter`

<pre />

#### `new`

<pre />

Creates an exporter writing `path` in `format`.

`root` confines the output and the file is owner-only, as for the ATOF and ATIF sinks: a trajectory carries prompt and response content.

#### `path`

<pre />

Returns the path this exporter writes to.

## Trait Implementations

### `impl Debug for OtlpFileSpanExporter`

#### `fmt`
