Struct ToolCallStartEvent 

pub struct ToolCallStartEvent {
    pub base: BaseEvent,
    pub tool_call_id: ToolCallId,
    pub tool_call_name: String,
    pub parent_message_id: Option<MessageId>,
}

Event indicating the start of a tool call.

This event is sent when the agent begins calling a tool with specific parameters. The tool_call_id identifies this call throughout the streaming process.

Fields

base: BaseEvent

Common event fields (timestamp, rawEvent).

tool_call_id: ToolCallId

Unique identifier for this tool call.

tool_call_name: String

Name of the tool being called.

parent_message_id: Option<MessageId>

Optional parent message ID if this call is part of a message.

Implementations

impl ToolCallStartEvent

pub fn new( tool_call_id: impl Into<ToolCallId>, tool_call_name: impl Into<String>, ) -> Self

Creates a new ToolCallStartEvent.

pub fn with_parent_message_id(self, message_id: impl Into<MessageId>) -> Self

Sets the parent message ID.

pub fn with_timestamp(self, timestamp: f64) -> Self

Sets the timestamp for this event.

Trait Implementations

impl Clone for ToolCallStartEvent

fn clone(&self) -> ToolCallStartEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ToolCallStartEvent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ToolCallStartEvent

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ToolCallStartEvent

fn eq(&self, other: &ToolCallStartEvent) -> 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.
