Struct ToolCallContentChunk 

#[non_exhaustive]
pub struct ToolCallContentChunk {
    pub tool_call_id: ToolCallId,
    pub content: ToolCallContent,
    pub meta: Option<Map<String, Value>>,
}

Available on crate feature unstable_protocol_v2 only.

A streamed item of tool-call content.

Tool-call content chunks append one ToolCallContent item to the current content for the matching ToolCallId. Agents can use ToolCallUpdate::content when they need to replace the whole content collection instead.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

tool_call_id: ToolCallId

The ID of the tool call this content belongs to.

content: ToolCallContent

A single item of content produced by the tool call.

meta: Option<Map<String, Value>>

The _meta property is reserved by ACP to allow clients and agents to attach additional metadata to their interactions. Implementations MUST NOT make assumptions about values at these keys. This field is optional; omitted or null means there is no chunk-level metadata.

See protocol docs: Extensibility

Implementations

impl ToolCallContentChunk

pub fn new( tool_call_id: impl Into<ToolCallId>, content: impl Into<ToolCallContent>, ) -> ToolCallContentChunk

Builds ToolCallContentChunk with the required fields set; optional fields start unset or empty.

pub fn meta( self, meta: impl IntoOption<Map<String, Value>>, ) -> ToolCallContentChunk

The _meta property is reserved by ACP to allow clients and agents to attach additional metadata to their interactions. Implementations MUST NOT make assumptions about values at these keys.

See protocol docs: Extensibility

Trait Implementations

impl Clone for ToolCallContentChunk

fn clone(&self) -> ToolCallContentChunk

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ToolCallContentChunk

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ToolCallContentChunk

fn deserialize<__D>( __deserializer: __D, ) -> Result<ToolCallContentChunk, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for ToolCallContentChunk

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 ToolCallContentChunk

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
