Struct git_hash::oid[][src]

#[repr(transparent)]
pub struct oid { /* fields omitted */ }
Expand description

A borrowed reference to a hash identifying objects.

Future Proofing

In case we wish to support multiple hashes with the same length we cannot discriminate using the slice length anymore. To make that work, we will use the high bits of the internal bytes slice length (a fat pointer, pointing to data and its length in bytes) to encode additinoal information. Before accessing or returning the bytes, a new adjusted slice will be constructed, while the high bits will be used to help resolving the hash [kind()][oid::kind()]. We expect to have quite a few bits available for such ‘conflict resolution’ as most hashes aren’t longer than 64 bytes.

Access

The kind of hash used for this Digest

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

Sha1 specific methods

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

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

Returns the bytes making up the Sha1.

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

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