Struct GeneratorCache 

pub struct GeneratorCache { /* private fields */ }

Generator cache. Held inside the registry; owned by the registry because cache invalidation hooks into registry mutations (registering a new command bumps the commands generator’s version, naturally invalidating cached entries via the new key).

Implementations

impl GeneratorCache

pub fn new() -> Self

pub fn get(&self, key: &CacheKey) -> Option<Vec<RawCandidate>>

Return cached candidates for key if present and not expired. Caller is responsible for cloning if it needs the returned Vec to outlive the cache; this signature returns an owned clone to avoid lock-poisoning footguns.

pub fn put(&self, key: CacheKey, candidates: Vec<RawCandidate>, ttl: Duration)

Store candidates under key with the given soft TTL.

pub fn invalidate(&self, key: &CacheKey)

Remove an entry. Used by tests and future explicit- invalidation paths.

pub fn clear(&self)

Drop every cached entry. Used by clear-completion-cache command (post-1.0) and in tests.

pub fn len(&self) -> usize

How many entries are currently cached. For tests + a future :cache-stats command.

pub fn is_empty(&self) -> bool
