unordered-containers: Efficient hashing-based container types
Efficient hashing-based container types. The containers have been optimized for performance critical use, both in terms of large data quantities and high speed.
The declared cost of each operation is either worst-case or amortized, but remains valid even if structures are shared.
Security
This package currently provides no defenses against hash collision attacks
such as HashDoS.
Users who need to store keys derived from untrusted input are advised to use
Data.Map or Data.Set from the containers package instead.
