val mem : t -> Reference.t -> bool Lwt.tmem state ref is true iff ref exists in state, otherwise it is false.
graph state is the graph containing all the references and their relationship in the current git repository state.
val normalize :
Hash.t Reference.Map.t ->
Reference.head_contents ->
(Hash.t, error) Stdlib.result Lwt.tnormalize graph ref is the final hash pointed by the reference ref. This function can return an error:
`Invalid_reference ref if, from the graph graph, we don't find the final pointed hash. This case can appear if the graph is not complete or if the link is broken.val list : t -> (Reference.t * Hash.t) list Lwt.tval remove : t -> Reference.t -> (unit, error) Stdlib.result Lwt.tremove state reference removes the reference reference from the git repository state.
val read :
t ->
Reference.t ->
(Reference.head_contents, error) Stdlib.result Lwt.tread state reference is the value contained in the reference reference (available in the git repository state).

Reference.t ->
Reference.head_contents ->
(unit, error) Stdlib.result Lwt.twrite state reference value writes the value value in the the reference in the git repository state.
