Trait DiscoveryCache 

pub trait DiscoveryCache: Send + Sync {
    // Required methods
    fn get(&self, key: &CacheKey) -> Result<Option<CacheValue>, PathError>;
    fn put(&self, key: CacheKey, value: CacheValue) -> Result<(), PathError>;
    fn invalidate(&self, root: &Path) -> Result<(), PathError>;
    fn clear(&self) -> Result<(), PathError>;
}

Trait for discovery result caches.

fn get(&self, key: &CacheKey) -> Result<Option<CacheValue>, PathError>

Get a cached value by key.

fn put(&self, key: CacheKey, value: CacheValue) -> Result<(), PathError>

Store a value.

fn invalidate(&self, root: &Path) -> Result<(), PathError>

Invalidate all keys whose root equals or is under root.

fn clear(&self) -> Result<(), PathError>

Clear the entire cache.
