Costruisce nuovo contenitore da una varietà di fonti di dati. Utilizza facoltativamente fornite dall'utente bucket_count da un numero minimo di segmenti per creare, hash come la funzione di hash, equal come la funzione per confrontare le chiavi e alloc come allocatore.
Original:
Constructs new container from a variety of data sources. Optionally uses user supplied bucket_count as a minimal number of buckets to create, hash as the hash function, equal as the function to compare keys and alloc as the allocator.
