Struct MapCache 

pub struct MapCache { /* private fields */ }

Map cache backed by the filesystem with LRU eviction.

Implementations

impl MapCache

pub fn new(cache_dir: PathBuf, default_ttl: Duration) -> Result<Self>

Create a new map cache in the given directory.

On creation, scans the cache directory for existing .ctx files and rebuilds the in-memory index so that previously cached maps are immediately available for lookup.

pub fn default_cache() -> Result<Self>

Create a cache with default settings (~/.cortex/maps/, 1 hour TTL).

pub fn get(&mut self, domain: &str) -> Option<&Path>

Get a cached map for the domain if it exists and is fresh.

pub fn put(&mut self, domain: &str, data: &[u8]) -> Result<PathBuf>

Cache a serialized map for the domain.

If the cache is full, the least-recently-used entry is evicted first.

pub fn cache_map(&mut self, domain: &str, map: &SiteMap) -> Result<PathBuf>

Cache a SiteMap by serializing it.

pub fn load_map(&mut self, domain: &str) -> Result<Option<SiteMap>>

Load a cached SiteMap for the domain.

pub fn load_all_maps(&mut self) -> Result<HashMap<String, SiteMap>>

Load all cached (non-expired) SiteMaps, returning a domain → SiteMap map.

pub fn invalidate(&mut self, domain: &str)

Invalidate (remove) a cached map.

pub fn len(&self) -> usize

Number of cached maps (including expired).

pub fn is_empty(&self) -> bool

Whether the cache is empty.

pub fn cleanup_expired(&mut self)

Remove all expired entries.

pub fn cache_dir(&self) -> &Path

Cache directory path.
