Vcs.Path_in_repoSourceA path for a file versioned in a repository.
This is a wrapper for a Fpath.t relative to the repo root, used for accrued type safety.
Given that t = string in the implementation, this function is just the identity.
of_string str returns Ok str if X.invariant str = true, and an error otherwise. This is meant to be used to validate untrusted entries.
v str is a convenient wrapper to build a t or raise Invalid_argument. This is typically handy for applying on trusted literals.
