Enum GitHashKind 

pub enum GitHashKind {
    Sha1,
    Sha256,
}

Which hash a repository’s object ids use. gunnar defaults to sha256 (D11); sha1 stays supported.

Variants

Sha1

Sha256

Implementations

impl GitHashKind

pub fn oid_len(self) -> usize

Raw oid length in bytes.

pub fn hex_len(self) -> usize

Hex oid length — the length of a relative_path in a git archive.

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

Infer the hash from a hex oid’s length. None for anything else.

pub fn code(self) -> u8

pub fn from_code(c: u8) -> Option<Self>

pub fn oid_of(self, canonical_bytes: &[u8]) -> Vec<u8>

The object id of these canonical bytes.

pub fn oid_of_object(self, kind: GitObjectKind, payload: &[u8]) -> Vec<u8>

The object id of (kind, payload) without building the canonical bytes: the "<type> <len>\0" header and the payload are fed to the hasher in two updates, so the resolver’s hot path allocates and copies nothing per object here (LAW: zero copy). Same oid as oid_of(&canonical(kind, payload)), and oid_of_object_is_oid_of_canonical holds the two together.

pub fn oid_hex_of(self, canonical_bytes: &[u8]) -> String

The hex object id of these canonical bytes.
