A t represents the edge from a child incremental to a parent expert node. A t is stateful, you cannot use the same t to link one child node to multiple parents at the same time.

val value : 'a t -> 'avalue t reads the value of the child incremental. It can only be used from the callback of the Expert.Node.t that has t in its set of dependencies.
