Enum HashAlgo 

pub enum HashAlgo {
    Sha1,
    Sha256,
}

A Git hash algorithm.

Git supports two object-id hash functions: the historical SHA-1 (20-byte digests, 40 hex chars) and the newer SHA-256 (32-byte digests, 64 hex chars). A repository’s algorithm is recorded in extensions.objectformat.

Variants

Sha1

SHA-1 — 20-byte digests.

Sha256

SHA-256 — 32-byte digests.

Implementations

impl HashAlgo

pub const fn len(self) -> usize

The raw digest length in bytes (20 for SHA-1, 32 for SHA-256).

pub const fn hex_len(self) -> usize

The hex-encoded digest length (40 for SHA-1, 64 for SHA-256).

pub const fn name(self) -> &'static str

The lowercase name as written in extensions.objectformat.

pub const fn oid_version(self) -> u8

The oid_version byte used in .idx/multi-pack-index headers (SHA-1 → 1, SHA-256 → 2).

pub fn from_name(name: &str) -> Option<Self>

Parse from the name used in extensions.objectformat config.

pub const fn from_len(len: usize) -> Option<Self>

The algorithm implied by a raw digest length, if recognised.

Trait Implementations

impl Clone for HashAlgo

fn clone(&self) -> HashAlgo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HashAlgo

impl Debug for HashAlgo

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

Formats the value using the given formatter.

impl Default for HashAlgo

fn default() -> HashAlgo

Returns the “default value” for a type.

impl Eq for HashAlgo

impl Hash for HashAlgo

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 Ord for HashAlgo

fn cmp(&self, other: &HashAlgo) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for HashAlgo

fn eq(&self, other: &HashAlgo) -> 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 PartialOrd for HashAlgo

fn partial_cmp(&self, other: &HashAlgo) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
