HASHKIT_CRC32(3)

💖 HASHKIT_CRC32(3) 💖

okay so bestie, welcome to hashkit_crc32 — the libhashkit documentation page that's lowkey the whole hash algorithm squad. this is from libmemcached-awesome and it's giving "one page, ten hash functions, zero notes". let's go 🦋

✨ NAME ✨

hashkit_crc32 — libhashkit Documentation. yes that's it, that's the name. short, sweet, iconic 💅

---

🌸 SYNOPSIS 🌸

first things first, you gotta pull in the header:

#include <libhashkit-1.0/hashkit.h>

and then, and this is important bestie, compile and link with -lhashkit. no -lhashkit, no vibes. 😭

here's the whole lineup of function signatures, character for character:

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)

that's eleven functions, one page, all of them take a const char *key and a size_t key_length and hand you back a uint32_t. the way they all match... coordinated. main character energy fr fr 👑

🎀 DESCRIPTION 🎀

so what are these little guys actually doing? these functions generate hash values from a key using a variety of algorithms. that's the whole deal. you give them a key, they give you a number. manifesting ✨

and the best part? they're flexible like that. these functions can be used standalone — like, you can just call one directly and go about your day — or they'll be used according to the algorithm set with hashkit_set_function() or hashkit_set_distribution_function(). so you can either pick your fave manually or let the library pick it for you. both valid, both slay. 🫶

⚠️ okay heads up, this is the important bit: the hashkit_hsieh(), hashkit_murmur() and hashkit_murmur3() functions are only available if the library is built with the appropriate flag enabled. so if those three are ghosting you, it's not personal, it's a build flag. build config said "not today" 💀

---

🌈 RETURN VALUE 🌈

a 32-bit hash value. that's it. that's the tea. ☕

and that's the page!! 🎉 the manual name is hashkit_crc32, it lives under section 3 of the manual, and the version info is literally 1.1 dated Jul 24, 2025 — and the source is the one and only libmemcached-awesome. periodt. 💖✨🌸🦋💅
