# Struct EndTool Handle Params

> Builder parameters for `NemoRelayContextState::build_tool_end_event`.

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 />

Builder parameters for [`NemoRelayContextState::build_tool_end_event`](/reference/api/rust-library-reference/nemo-relay/api/runtime/state/struct-nemorelaycontextstate).

## Fields

### `handle: &'a ToolHandle`

Tool handle to serialize into the emitted end event.

### `data: Option<Json>`

Optional data payload merged over the handle data.

### `metadata: Option<Json>`

Optional metadata payload merged over the handle metadata.

### `timestamp: Option<DateTime<Utc>>`

Optional timestamp recorded on the emitted end event. When omitted, the runtime records the current UTC time, or one microsecond after the handle start time if the current time is not later.

## Implementations

### `impl<'a> EndToolHandleParams<'a>`

<pre />

#### `builder`

<pre />

Create a builder for building `EndToolHandleParams`. On the builder, call `.handle(...)`, `.data(...)`(optional), `.metadata(...)`(optional), `.timestamp(...)`(optional) to set the values of the fields. Finally, call `.build()` to create the instance of `EndToolHandleParams`.
