Struct FunctionCallContent 

pub struct FunctionCallContent {
    pub call_id: String,
    pub name: String,
    pub arguments: Option<FunctionArguments>,
    pub protected_data: Option<String>,
}

A request from the model to call a tool/function.

arguments may be a partial JSON string (during streaming) or a completed JSON object.

Fields

call_id: String

name: String

arguments: Option<FunctionArguments>

protected_data: Option<String>

Provider-opaque replay token attached to this call, base64.

The counterpart of TextReasoningContent::protected_data. Gemini 3 returns a thoughtSignature on the part carrying the function call — the usual placement — and requires it echoed when the call is replayed; a signature on a preceding thought part is the fallback. Absent for providers that do not use one.

Implementations

impl FunctionCallContent

pub fn new( call_id: impl Into<String>, name: impl Into<String>, arguments: Option<FunctionArguments>, ) -> FunctionCallContent

pub fn with_protected_data( self, protected_data: Option<String>, ) -> FunctionCallContent

Attach a provider-opaque replay token (see Self::protected_data).

pub fn parse_arguments(&self) -> Result<HashMap<String, Value>, Error>

Parse the arguments into a JSON object map.

pub fn merge(&mut self, other: &FunctionCallContent) -> Result<(), Error>

Merge a streamed continuation of the same call into this one.
