Module type `CCGraph.MAP`

type vertex
type 'a t

val as_graph : 'a t -> (vertex, 'a) graph: Graph view of the map.

val empty : 'a t
val add_edge : vertex -> 'a -> vertex -> 'a t -> 'a t
val remove_edge : vertex -> vertex -> 'a t -> 'a t
val add : vertex -> 'a t -> 'a t: Add a vertex, possibly with no outgoing edge.

val remove : vertex -> 'a t -> 'a t: Remove the vertex and all its outgoing edges. Edges that point to the vertex are NOT removed, they must be manually removed with remove_edge.
