bit_array_digest

pub fn bit_array_digest(hash: Hash) -> BitArray

Returns 32 bit digest of the hash as a BitArray.

hash_string("murmur3a", 0)
|> bit_array_digest
// -> <<232, 177, 21, 28>>

</>

pub fn hash_bytes(key: BitArray, seed: Int) -> Result(Hash, Nil)

Computes a 32 bit Murmur3 hash of the supplied bit array.

Returns Error(Nil) if the bit array is not byte-aligned.

hash_bytes(<<"murmur3a">>, 0)
// -> Ok(Hash(3521997819, 0, -391047908))

</>

pub fn hash_ints(key: List(Int), seed: Int) -> Hash

Computes a 32 bit Murmur3 hash of the supplied list of integers.

Note: Values outside the 0–255 range will be truncated to their lowest byte before hashing.

hash_ints([1, 2, 3], 0)
// -> Hash(0, 24, -2133732860)

</>

pub fn hash_string(key: String, seed: Int) -> Hash

Computes a 32 bit Murmur3 hash of the input string.

hash_string("murmur3a", 0)
// -> Hash(3521997819, 0, -391047908)

</>

pub fn hex_digest(hash: Hash) -> String

Returns a hexadecimal digest of the hash.

hash_string("murmur3a", 0)
|> hex_digest
// -> "E8B1151C"

</>

pub fn int_digest(hash: Hash) -> Int

Returns the 32 bit signed integer digest of the hash.

Keep in mind that these values may return negative numbers!

hash_ints([1, 2, 3], 0)
|> int_digest
// -> -2133732860
