hash.fnv1a #

This module implements a FNV-1a hash. (see https://en.wikipedia.org/wiki/Fowler–Noll–Vo_hash_function)

fn new_fnv1a64() &Fnv1a64

new_fnv1a64 creates an Fnv1a64 in its initial (offset-basis) state.

fn sum32(data []u8) u32

sum32 returns a fnv1a hash of the memory block, described by the dynamic byte array data.

fn sum32_bytes(data &u8, data_len int) u32

sum32_bytes returns a fnv1a hash of data_len bytes starting at the address in the given &u8 pointer data.

fn sum32_string(data string) u32

sum32 returns a fnv1a hash of the string, described by data

fn sum32_struct[T](s &T) u32

sum32_bytes returns a fnv1a hash of the struct s.

fn sum64(data []u8) u64

sum64 returns a fnv1a hash of the memory block, described by the dynamic byte array data.

fn sum64_bytes(data &u8, data_len int) u64

sum64_bytes returns a fnv1a hash of data_len bytes starting at the address in the given &u8 pointer data.

fn sum64_string(data string) u64

sum64 returns a fnv1a hash of the string, described by data

fn sum64_struct[T](s &T) u64

sum64_bytes returns a fnv1a hash of the struct s.

struct Fnv1a64 {
mut:
	state u64
}

Fnv1a64 is a streaming FNV-1a 64-bit hasher. It implements hash.Hasher: bytes are absorbed with write and the digest is read any number of times with finish.

fn (mut h Fnv1a64) write(p []u8) !

write absorbs bytes into the hash state.

fn (h &Fnv1a64) finish() u64

finish returns the current 64-bit digest without consuming state.

fn (h &Fnv1a64) sum(data []u8) u64

sum returns the FNV-1a 64-bit digest of data in one shot.
