Enum HashType 

pub enum HashType {
    OneAtATime,
    Md5,
    Crc16,
    Crc32,
    Crc32a,
    Fnv1_64,
    Fnv1a64,
    Fnv1_32,
    Fnv1a32,
    Hsieh,
    Murmur,
    Jenkins,
    Murmur3,
    Murmur3X64_64,
}

Hash algorithm selected by hash:.

The names mirror the algorithm tags accepted by the YAML parser. Stage 3 owns the hashing math; this enum models only the configured choice so the parser can echo it back without depending on the hashkit module.

Examples

use dynomite::conf::HashType;
assert_eq!(HashType::parse("murmur3").unwrap(), HashType::Murmur3);
assert_eq!(HashType::Md5.as_str(), "md5");

Variants

OneAtATime

One-at-a-time hash.

Md5

MD5 (truncated for ketama).

Crc16

CRC-16.

Crc32

CRC-32.

Crc32a

CRC-32 ARM.

Fnv1_64

64-bit FNV-1.

Fnv1a64

64-bit FNV-1a.

Fnv1_32

32-bit FNV-1.

Fnv1a32

32-bit FNV-1a.

Hsieh

Paul Hsieh’s hash.

Murmur

Murmur hash (32-bit, version 1).

Jenkins

Bob Jenkins’s hash.

Murmur3

Murmur hash 3 (128-bit).

Murmur3X64_64

MurmurHash3 truncated to 64 bits (used by random slicing).

Implementations

impl HashType

pub fn parse(s: &str) -> Result<Self, ConfError>

Parse a hash: value (case-sensitive).

Examples

use dynomite::conf::HashType;
assert_eq!(HashType::parse("fnv1a_64").unwrap(), HashType::Fnv1a64);
assert!(HashType::parse("FNV1A_64").is_err());

pub fn as_str(self) -> &'static str

Render back to the canonical YAML name.

Examples

use dynomite::conf::HashType;
assert_eq!(HashType::Crc32a.as_str(), "crc32a");

Trait Implementations

impl Clone for HashType

fn clone(&self) -> HashType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HashType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for HashType

fn deserialize<D: Deserializer<'de>>(de: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for HashType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for HashType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for HashType

fn eq(&self, other: &HashType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for HashType

fn serialize<S: Serializer>(&self, ser: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl Copy for HashType

impl Eq for HashType

impl StructuralPartialEq for HashType
