CacheStrategy

Enum CacheStrategy 

Source
pub enum CacheStrategy {
    None,
    Auto,
    Anthropic,
    Google {
        ttl: Duration,
    },
}
Expand description

Provider-agnostic caching configuration.

Adapters translate this to provider-specific cache markers at request construction time. Adapters that don’t support caching silently ignore the strategy.

Variants§

§

None

No caching (default) — no cache markers injected.

§

Auto

Adapter determines optimal cache points (e.g., system prompt + tool definitions for Anthropic, long context for Google).

§

Anthropic

Anthropic-specific: inject cache_control: { type: "ephemeral" } blocks on system prompt and tool definitions.

§

Google

Google-specific: reference a CachedContent resource with the given TTL.

Fields

§ttl: Duration

Time-to-live for the cached content.
