size :: HashTable s k v -> ST s Int

hashtables Data.HashTable.ST.Basic

Returns the number of mappings currently stored in this table. O(1)

fromListWithSizeHint :: (HashTable h, Eq k, Hashable k) => Int -> [(k, v)] -> ST s (h s k v)

hashtables Data.HashTable.Class

Create a hash table from a list of key-value pairs, with a size hint. O(n).

newSized :: HashTable h => Int -> ST s (h s k v)

hashtables Data.HashTable.Class

Creates a new hash table sized to hold n elements. O(n).
