}

Granular events emitted by the assistant during a streaming turn.

Carried inside RpcEvent::MessageUpdate.

Variants

TextDelta

An incremental text chunk from the assistant’s response.

Fields

delta: String

The text fragment.

ThinkingDelta

An incremental thinking/reasoning chunk (extended thinking mode).

Fields

delta: String

The thinking fragment.

ToolcallStart

A tool call has started streaming. Subsequent AssistantEvent::ToolcallInputDelta frames carry the JSON input.

Fields

tool_id: String

Model-assigned opaque identifier for this tool call.

tool_name: String

The tool being invoked.

ToolcallInputDelta

An incremental JSON fragment of a tool call’s input.

Fields

tool_id: String

Matches the tool_id from AssistantEvent::ToolcallStart.

delta: String

Raw JSON fragment (not yet a complete object).

ToolcallInput

The complete, finalised input for a tool call.

Fields

tool_id: String

Matches the tool_id from AssistantEvent::ToolcallStart.

input: Value

The fully parsed JSON input value.

ToolcallResult

The result returned by tool execution.

Fields

tool_id: String

Matches the tool_id from AssistantEvent::ToolcallStart.

result: String

The serialised tool result string.

Trait Implementations

impl Clone for AssistantEvent

fn clone(&self) -> AssistantEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AssistantEvent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AssistantEvent

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AssistantEvent

fn eq(&self, other: &AssistantEvent) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for AssistantEvent

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
