Struct ChatToolFunction

Source 
pub struct ChatToolFunction {
    pub name: String,
    pub description: Option<String>,
    pub parameters: Option<Value>,
    pub strict: Option<bool>,
}

Fields§

§name: String

The name of the function to be called. Must be a-z, A-Z, 0-9, or contain underscores and dashes, with a maximum length of 64.

§description: Option<String>

A description of what the function does, used by the model to choose when and how to call the function.

§parameters: Option<Value>

The parameters the functions accepts, described as a JSON Schema object. See the guide for examples, and the JSON Schema reference for documentation about the format.

Omitting parameters defines a function with an empty parameter list.

§strict: Option<bool>

Whether to enable strict schema adherence when generating the function call. If set to true, the model will follow the exact schema defined in the parameters field. Only a subset of JSON Schema is supported when strict is true. Learn more about Structured Outputs in the function calling guide.
