This corresponds to ToolMessageChunk in LangChain Python.

Implementations

impl ToolMessageChunk

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

Create a new tool message chunk.

pub fn content(&self) -> &str

Get the message content.

pub fn tool_call_id(&self) -> &str

Get the tool call ID.

pub fn id(&self) -> Option<&str>

Get the message ID.

pub fn name(&self) -> Option<&str>

Get the tool name.

pub fn status(&self) -> &ToolStatus

Get the status.

pub fn artifact(&self) -> Option<&Value>

Get the artifact.

pub fn concat(&self, other: &ToolMessageChunk) -> ToolMessageChunk

Concatenate this chunk with another chunk.

pub fn to_message(&self) -> ToolMessage

Convert this chunk to a complete ToolMessage.

Trait Implementations

impl Add for ToolMessageChunk

type Output = ToolMessageChunk

The resulting type after applying the + operator.

fn add(self, other: ToolMessageChunk) -> ToolMessageChunk

Performs the + operation.

impl Clone for ToolMessageChunk

fn clone(&self) -> ToolMessageChunk

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ToolMessageChunk

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ToolMessageChunk

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<ToolMessageChunk> for BaseMessageChunk

fn from(chunk: ToolMessageChunk) -> Self

Converts to this type from the input type.

impl PartialEq for ToolMessageChunk

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
