Enum ToolChoice

pub enum ToolChoice {
    Any,
    Auto,
    Tool(String),
    None,
}

Tool choice determines how the LLM uses available tools. The behavior is standardized across different LLM providers.

Variants

Any

Model can use any tool, but it must use at least one. This is useful when you want to force the model to use tools.

Auto

Model can use any tool, and may elect to use none. This is the default behavior and gives the model flexibility.

Tool(String)

Model must use the specified tool and only the specified tool. The string parameter is the name of the required tool. This is useful when you want the model to call a specific function.

None

Explicitly disables the use of tools. The model will not use any tools even if they are provided.
