Eio_mock.Handler
Control how a mock responds.
This module is mostly useful when writing custom mocks. Individual mocks usually provide convenience wrappers around this.
type 'a actions = 'a Action.t list
make default_action
is a new handler that initially always runs default_action
.
val set_handler : 'a t -> (unit -> 'a) -> unit
set_handler t fn
sets (replaces) the function to be called whenever the handler is run.
seq t actions
sets a handler function that performs the next action in actions
on each call. When there are no more actions, it runs the default handler.
val run : 'a t -> 'a
run t
is used by mocks to run their handlers.
