Struct gix::oid

pub struct oid { /* private fields */ }

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 additional 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(). We expect to have quite a few bits available for such ‘conflict resolution’ as most hashes aren’t longer than 64 bytes.
