State_builder.Hashtbl
module H : Datatype.Hashtbl
module Data : Datatype.S
module Info : Info_with_size
Hashtbl are a standard computation. BUT that is INCORRECT to use projectified hashtables if keys have a custom rehash
function (see Project
.DATATYPE_OUTPUT.rehash)
include S with module Datatype = H.Make(Data)
val self : State.t
The kind of the registered state.
val mark_as_computed : ?project:Project.t -> unit -> unit
Indicate that the registered state will not change again for the given project (default is current ()
).
val is_computed : ?project:Project.t -> unit -> bool
Returns true
iff the registered state will not change again for the given project (default is current ()
).
Exportation of some inputs (easier use of State_builder.Register
).
module Datatype = H.Make(Data)
val add_hook_on_update : ( Datatype.t -> unit ) -> unit
Add an hook which is applied each time (just before) the project library changes the local value of the state.
val howto_marshal : ( Datatype.t -> 'a ) -> ( 'a -> Datatype.t ) -> unit
howto_marshal marshal unmarshal
registers a custom couple of functions (marshal, unmarshal)
to be used for serialization. Default functions are identities. In particular, this function must be used if Datatype.t
is not marshallable and do_not_save
is not called.
type key = H.key
type data = Data.t
Memoization. Compute on need the data associated to a given key using the given function. If the data is already computed, it is possible to change with change
.
val mem : key -> bool
val remove : key -> unit
