# Type Alias Tool Sanitize Fn

> Sanitize a tool request payload before the runtime records it.

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`.

<pre />

Sanitize a tool request payload before the runtime records it.

Tool sanitize callbacks are used only for observability payloads. They can rewrite the JSON arguments recorded on tool-start events without changing the caller-owned request that is passed to the tool implementation.

## Parameters

* First argument: Tool name associated with the request payload.
* Second argument: JSON payload to sanitize for observability.

## Returns

Sanitized JSON payload for the emitted event.

## Aliased Type

```rust
pub struct ToolSanitizeFn { /* private fields */ }
```
