HASHKIT_FNV1_64(3)

💖 HASHKIT_FNV1_64 💖

okay bestie, welcome to the libmemcached-awesome section 3 club 🎀 this lil page lives under the name hashkit_fnv1_64 and it's your one-stop for making hash values out of keys. it's giving "libhashkit Documentation" energy and we are obsessed 💅

✨ NAME ✨

hashkit_fnv1_64 — the libhashkit documentation moment, fr fr 🦋

---

🌸 SYNOPSIS 🌸

first things first, you gotta pull in the header and link the lib:

#include <libhashkit-1.0/hashkit.h>
       Compile and link with -lhashkit

and here's the whole squad of hash functions, exactly as they are, no cap:

uint32_t hashkit_default(const char *key, size_t key_length)

uint32_t hashkit_fnv1_64(const char *key, size_t key_length)

uint32_t hashkit_fnv1a_64(const char *key, size_t key_length)

uint32_t hashkit_fnv1_32(const char *key, size_t key_length)

uint32_t hashkit_fnv1a_32(const char *key, size_t key_length)

uint32_t hashkit_crc32(const char *key, size_t key_length)

uint32_t hashkit_hsieh(const char *key, size_t key_length)

uint32_t hashkit_murmur(const char *key, size_t key_length)

uint32_t hashkit_murmur3(const char *key, size_t key_length)

uint32_t hashkit_jenkins(const char *key, size_t key_length)

uint32_t hashkit_md5(const char *key, size_t key_length)

like look at them all, a whole little friend group 🫶 each one takes a key and a key_length and does its thing.

👑 DESCRIPTION 👑

so here's the tea ☕ these functions generate hash values from a key using a variety of algorithms. you can use them standalone if you want, or they'll get used automatically according to whichever algorithm you set with hashkit_set_function() or hashkit_set_distribution_function(). main character behavior honestly 💜

and now the important caveat, listen up:

the hashkit_hsieh(), hashkit_murmur() and hashkit_murmur3() functions are only available if the library is built with the appropriate flag enabled. like, if you didn't build it with that flag, they're just... not there. periodt. 💀

---

🌈 RETURN VALUE 🌈

a 32-bit hash value. that's it, that's the whole vibe ✨
