Struct FunctionDeclaration 

pub struct FunctionDeclaration {
    pub name: String,
    pub description: String,
    pub parameters: Option<Value>,
    pub behavior: Option<FunctionCallingBehavior>,
}

Schema for a single function that the model can call.

Examples

use gemini_genai_rs::protocol::types::FunctionDeclaration;
use serde_json::json;

let decl = FunctionDeclaration {
    name: "get_weather".to_string(),
    description: "Get weather for a city".to_string(),
    parameters: Some(json!({
        "type": "object",
        "properties": { "city": { "type": "string" } },
        "required": ["city"]
    })),
    behavior: None,
};

Fields

name: String

Function name.

description: String

Human-readable description for the model.

parameters: Option<Value>

JSON Schema describing function parameters.

behavior: Option<FunctionCallingBehavior>

Per-function calling behavior override.

When set to NonBlocking, the model continues generating while this function executes asynchronously. The response can then include a super::enums::FunctionResponseScheduling to control how results are delivered.

Trait Implementations

impl Clone for FunctionDeclaration

fn clone(&self) -> FunctionDeclaration

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionDeclaration

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FunctionDeclaration

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FunctionDeclaration

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

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.
