Enum DeferrablePolicy 

pub enum DeferrablePolicy {
    Never,
    Automatic,
    Always,
}

Controls whether a tool’s full schema can be deferred (tool_search).

When tool_search is active and a model supports it, tools marked as Automatic or Always will have defer_loading: true set, meaning only the name+description are sent upfront and full parameter schemas are loaded on-demand by the model.

Variants

Never

Never defer — always send full schema (e.g., high-frequency tools like write_todos)

Automatic

Let the driver decide based on tool count threshold (default)

Always

Always defer when tool_search is active, regardless of threshold
