Module `Expert.Dependency`

type ('a, 'w) t: 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 sexp_of_t : ('a -> Ppx_sexp_conv_lib.Sexp.t) -> ('w -> Ppx_sexp_conv_lib.Sexp.t) -> ('a, 'w) t -> Ppx_sexp_conv_lib.Sexp.t

val create : ?⁠on_change:('a -> unit) -> ('a, 'w) incremental -> ('a, 'w) t: When calling create ?on_change child, nothing happens until the t is linked to a parent. see Node.add_dependency for documentation of on_change.

val value : ('a, _) t -> 'a: value 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.
