Struct ToolCall 

pub struct ToolCall {
    pub id: String,
    pub call_id: Option<String>,
    pub function: ToolFunction,
    pub signature: Option<String>,
    pub additional_params: Option<Value>,
}

Describes a tool call with an id and function to call, generally produced by a provider.

Fields

id: String

Provider-supplied tool call ID.

call_id: Option<String>

Provider-specific call ID used by some APIs for tool result correlation.

function: ToolFunction

Function name and JSON arguments requested by the model.

signature: Option<String>

Optional cryptographic signature for the tool call.

This field is used by some providers (e.g., Google) to provide a signature that can verify the authenticity and integrity of the tool call. When present, it allows verification that the tool call was actually generated by the model and has not been tampered with.

This is an optional, provider-specific feature and will be None for providers that don’t support tool call signatures.

additional_params: Option<Value>

Additional provider-specific parameters to be sent to the completion model provider

Implementations

impl ToolCall

pub fn new(id: String, function: ToolFunction) -> Self

Trait Implementations

impl Clone for ToolCall

fn clone(&self) -> ToolCall

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ToolCall

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ToolCall

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<RawStreamingToolCall> for ToolCall

fn from(tool_call: RawStreamingToolCall) -> Self

Converts to this type from the input type.

impl From<ToolCall> for FunctionCall

fn from(tool_call: ToolCall) -> Self

Converts to this type from the input type.

impl From<ToolCall> for Message

fn from(tool_call: ToolCall) -> Self

Converts to this type from the input type.

impl From<ToolCall> for Part

fn from(tool_call: ToolCall) -> Self

Converts to this type from the input type.

impl From<ToolCall> for ToolCall

fn from(tool_call: ToolCall) -> Self

Converts to this type from the input type.

impl From<ToolCall> for ToolCall

fn from(value: ToolCall) -> Self

Converts to this type from the input type.

impl From<ToolCall> for ToolCall

fn from(value: ToolCall) -> Self

Converts to this type from the input type.

impl From<ToolCall> for ToolCall

fn from(tool_call: ToolCall) -> Self

Converts to this type from the input type.

impl From<ToolCall> for ToolCall

fn from(tool_call: ToolCall) -> Self

Converts to this type from the input type.

impl From<ToolCall> for ToolCall

fn from(tool_call: ToolCall) -> Self

impl PartialEq for ToolCall

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
