Struct git_hash::borrowed::Digest

pub struct Digest<'a>(_);

A borrowed reference to a hash identifying objects.

Implementations

impl<'a> Digest<'a>

Access

pub fn kind(&self) -> Kind

The kind of hash used for this Digest

pub fn first_byte(&self) -> u8

The first byte of the hash, commonly used to partition a set of Digests

impl<'a> Digest<'a>

Sha1 specific methods

pub fn to_sha1_hex(&self) -> [u8; 40]

Returns an array with a hexadecimal encoded version of the Sha1 hash this Digest represents.

Panics if this is not a Sha1 hash, as identifiable by Digest::kind().

pub fn sha1(&self) -> &[u8; 20]

Returns the bytes making up the Sha1.

Panics if this is not a Sha1 hash, as identifiable by Digest::kind().

pub fn null_sha1() -> Self

Returns a Sha1 digest with all bytes being initialized to zero.

Trait Implementations

impl<'a> Clone for Digest<'a>

pub fn clone(&self) -> Digest<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for Digest<'a>

impl<'a> Debug for Digest<'a>

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

Formats the value using the given formatter.

impl<'de: 'a, 'a> Deserialize<'de> for Digest<'a>

Manually created from a version that uses a slice, and we forcefully try to convert it into a borrowed array of the desired size Could be improved by fitting this into serde Unfortunately the serde::Deserialize derive wouldn't work for borrowed arrays.

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

Deserialize this value from the given Serde deserializer.

impl Display for Digest<'_>

impl<'a> Hash for Digest<'a>

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

Feeds this value into the given Hasher.
