pub fn instance_of(git_dir: &Path) -> StringExpand description
What: The instance name of a worktree: 32 hexadecimal digits of the FNV-1a hash of its real Git directory path. Why: The real path makes two spellings of one directory (a link, a relative part) one instance. A directory that cannot be resolved is hashed as given.
In TS you’d write (pseudocode):
instanceOf(gitDir) // '3f9a...' (32 digits)
