module Input : sig ... endval init : Input.t -> Js_of_ocaml.Dom_html.element Js_of_ocaml.Js.t -> State.tinit is called the first time that this attribute is attached to a particular node. It is particularly responsible for producing a value of type State.t. The element that it is being attached to is not necessarily attached to the rest of the DOM tree.
val on_mount :
Input.t ->
State.t ->
Js_of_ocaml.Dom_html.element Js_of_ocaml.Js.t ->
uniton_mount is called once, after the element is attached to the rest of the DOM tree.
val update :
old_input:Input.t ->
new_input:Input.t ->
State.t ->
Js_of_ocaml.Dom_html.element Js_of_ocaml.Js.t ->
unitupdate is called when a previous attribute of the same kind existed on the vdom node. You get access to the Input.t that the previous node was created with, as well as the State.t for that hook, which you can mutate if you like. There is no guarantee that update will be called instead of a sequence of destroy followed by init, so update should behave the same as that sequence (except it might be faster).
val destroy :
Input.t ->
State.t ->
Js_of_ocaml.Dom_html.element Js_of_ocaml.Js.t ->
unitdestroy is called when the previous vdom has this hook, but a newer vdom tree does not. The last input and state are passed in alongside the element that it used to be attached to.
