Struct ToolCallChunkEvent 

pub struct ToolCallChunkEvent {
    pub base: BaseEvent,
    pub tool_call_id: Option<ToolCallId>,
    pub tool_call_name: Option<String>,
    pub parent_message_id: Option<MessageId>,
    pub delta: Option<String>,
    pub subagent_run_id: Option<SubagentRunId>,
}

A self-contained tool-call update: start, args and end folded into one.

Fields

base: BaseEvent

Timestamp and raw provider event.

tool_call_id: Option<ToolCallId>

The call this chunk belongs to.

tool_call_name: Option<String>

Name of the tool being called.

parent_message_id: Option<MessageId>

The assistant message that requested the call. A JSON null reads as absent, as in ToolCallStartEvent.

delta: Option<String>

The argument-JSON fragment.

subagent_run_id: Option<SubagentRunId>

The subagent that produced this event; absent means the parent agent. A JSON null is rejected — see crate::event::subagent.

Implementations

impl ToolCallChunkEvent

pub fn new( tool_call_id: Option<ToolCallId>, tool_call_name: Option<String>, delta: Option<String>, ) -> Self

Builds a chunk carrying a call id, tool name and argument delta.

Trait Implementations

impl Clone for ToolCallChunkEvent

fn clone(&self) -> ToolCallChunkEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ComposeSchema for ToolCallChunkEvent

fn compose(generics: Vec<RefOr<Schema>>) -> RefOr<Schema>

impl Debug for ToolCallChunkEvent

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

Formats the value using the given formatter.

impl Default for ToolCallChunkEvent

fn default() -> ToolCallChunkEvent

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ToolCallChunkEvent

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<ToolCallChunkEvent> for Event

fn from(payload: ToolCallChunkEvent) -> Self

Converts to this type from the input type.

impl JsonSchema for ToolCallChunkEvent

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for ToolCallChunkEvent

fn eq(&self, other: &ToolCallChunkEvent) -> 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 ToolCallChunkEvent

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for ToolCallChunkEvent

impl ToSchema for ToolCallChunkEvent

fn name() -> Cow<'static, str>

Return name of the schema.

fn schemas(schemas: &mut Vec<(String, RefOr<Schema>)>)

Implement reference [utoipa::openapi::schema::Schema]s for this type.
