Trait Implementations

impl CacheAccessor<TableScopedPath, Arc<Vec<ObjectMeta>>> for DefaultListFilesCache

fn get(&self, k: &TableScopedPath) -> Option<Arc<Vec<ObjectMeta>>>

Gets all files for the given table base path.

This is equivalent to calling get_with_extra(k, &None).

fn get_with_extra( &self, table_scoped_path: &TableScopedPath, prefix: &Self::Extra, ) -> Option<Arc<Vec<ObjectMeta>>>

Performs a prefix-aware cache lookup.

Arguments

• table_base - The table’s base path (the cache key)
• prefix - Optional prefix filter (relative to table base) for partition filtering

Behavior

• Fetches the cache entry for table_base
• If prefix is Some, filters results to only files matching table_base/prefix
• Returns the (potentially filtered) results

This enables efficient partition pruning - a single cached listing of the full table can serve queries for any partition subset without additional storage calls.

type Extra = Option<Path>

fn put( &self, key: &TableScopedPath, value: Arc<Vec<ObjectMeta>>, ) -> Option<Arc<Vec<ObjectMeta>>>

Put value into cache. Returns the old value associated with the key if there was one.

fn put_with_extra( &self, key: &TableScopedPath, value: Arc<Vec<ObjectMeta>>, _e: &Self::Extra, ) -> Option<Arc<Vec<ObjectMeta>>>

Put value into cache. Returns the old value associated with the key if there was one.

fn remove(&self, k: &TableScopedPath) -> Option<Arc<Vec<ObjectMeta>>>

Remove an entry from the cache, returning value if they existed in the map.

fn contains_key(&self, k: &TableScopedPath) -> bool

Check if the cache contains a specific key.

fn len(&self) -> usize

Fetch the total number of cache entries.

fn clear(&self)

Remove all entries from the cache.

fn name(&self) -> String

Return the cache name.

fn is_empty(&self) -> bool

Check if the Cache collection is empty or not.

impl Clone for TableScopedPath

fn clone(&self) -> TableScopedPath

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TableScopedPath

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for TableScopedPath

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TableScopedPath

fn eq(&self, other: &TableScopedPath) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
