The various types of objects in git.

View Source 
const Missing = "0000000000000000000000000000000000000000"

Missing is a sentinel zero-value for object id (aka sha). Git treats this value as "this thing doesn't exist". For example, when updating a ref, if the old value is specified as EmptyOid, Git will refuse to update the ref if already exists.

type UpstreamStatus 

type UpstreamStatus string

UpstreamStatus is the status of a git ref (usually a branch) relative to its upstream.
