XX hash

XXHash64

XXHash64 is a fast and efficient non-cryptographic hash function for 64-bit platforms. It is designed for producing a quick and reliable hash value for a given data, which can be used for many applications, such as checksum, data validation, etc. In addition, it has a good distribution of hash values, which helps to reduce collisions.

Extensions

XXHash64StringExtension on String

Extension to String to generate xxh64 code.

Constants

xxh64 → const XXHash64

An instance of XXHash64 with seed = 0

Functions

xxh64code(String input, [Encoding? encoding]) → int

Gets the 64-bit xxHash value of a String.

xxh64sum(String input, [Encoding? encoding]) → String

Gets the 64-bit xxHash hash of a String in hexadecimal.
