Struct OpenAiPlanCache 

pub struct OpenAiPlanCache { /* private fields */ }

In-memory store of plan evaluation responses keyed by PlanCacheKey.

Implementations

impl OpenAiPlanCache

pub fn new() -> Self

Returns an empty plan cache.

pub fn get(&self, key: &PlanCacheKey) -> Option<&Expr>

Returns the cached response for key, or None when absent.

pub fn put( &mut self, cx: &mut Cx, target: PlanCacheWriteTarget, key: PlanCacheKey, response: Expr, ) -> Result<()>

Inserts a response under key, checking the cache capability when persistent.

Writes to PlanCacheWriteTarget::Persistent require the runner cache capability and fail closed if it is not granted; memory writes always succeed.

pub fn len(&self) -> usize

Returns the number of cached entries.

pub fn is_empty(&self) -> bool

Returns true when the cache holds no entries.
