static constexpr hash32	crc32 (const char *str, hash32 prev_crc=0xFFFFFFFF)
	Computes the CRC32 hash of a string at compile time.

Detailed Description

template<int size, int idx = 0, class dummy = void>
struct z::core::hash32gen< size, idx, dummy >

A compile-time CRC32 hash function.

This template recursively computes the CRC32 hash of a string at compile time. To use this, call constexpr auto your_var = HASH32("your_string") with a string literal. It will also work with strings that aren't known at compile time, but the result will of course be computed at runtime.
