Struct ContextCacheConfig 

pub struct ContextCacheConfig {
    pub min_tokens: u32,
    pub ttl_seconds: u32,
    pub cache_intervals: u32,
}

Configuration for automatic prompt caching lifecycle management.

When set on runner configuration, the runner will automatically create and manage cached content resources for supported providers (currently Gemini).

Example

use adk_core::ContextCacheConfig;

let config = ContextCacheConfig {
    min_tokens: 4096,
    ttl_seconds: 600,
    cache_intervals: 3,
};
assert_eq!(config.min_tokens, 4096);

Fields

min_tokens: u32

Minimum system instruction + tool token count to trigger caching. Set to 0 to disable caching.

ttl_seconds: u32

Cache time-to-live in seconds. Set to 0 to disable caching.

cache_intervals: u32

Maximum number of LLM invocations before cache refresh. After this many invocations, the runner creates a new cache and deletes the old one.
