val list : t -> (Reference.t * Hash.t) list Lwt.tlist state returns an associated list between reference and its bind hash.
val mem : t -> Reference.t -> bool Lwt.tmem state ref returns true iff ref exists in state, otherwise returns false.
val read : t -> Reference.t -> (Reference.head_contents, error) result Lwt.tread state reference returns the value contains in the reference reference (available in the git repository state).
resolve state reference returns endpoint of reference (available in the git repository state).
val write :
t ->
Reference.t ->
Reference.head_contents ->
(unit, error) result Lwt.twrite state reference value writes the value value in the mutable representation of the reference in the git repository state.
val remove : t -> Reference.t -> (unit, error) result Lwt.tremove state reference removes the reference reference from the git repository state.
