Implementations

impl AsyncArrayShardedReadableExtCache

pub fn new<TStorage: ?Sized + AsyncReadableStorageTraits>( array: &Array<TStorage>, ) -> Self

Create a new cache for an array.

pub fn array_is_sharded(&self) -> bool

Returns true if the array is sharded.

This is cheaper than calling ArrayShardedExt::is_sharded repeatedly.

pub fn array_is_exclusively_sharded(&self) -> bool

Returns true if the array is exclusively sharded (no array-to-array or bytes-to-bytes codecs).

This is cheaper than calling ArrayShardedExt::is_exclusively_sharded repeatedly.

pub async fn len(&self) -> usize

Return the number of shard indexes cached.

pub async fn is_empty(&self) -> bool

Returns true if the cache contains no cached shard indexes.

pub async fn clear(&self)

Clear the cache.
