Module Lwt_pqueue.Make

Parameters
Signature

Instructions: Use this module in your project

In the IDE (CLion, Visual Studio Code, Xcode, etc.) you use for your DkSDK project:

Add the following to your project's dependencies/CMakeLists.txt:

Copy

DkSDKProject_DeclareAvailable(lwt
    CONSTRAINT "= 5.6.1"
    FINDLIBS lwt lwt.unix)
DkSDKProject_MakeAvailable(lwt)

Add the Findlib::lwt library to any desired targets in src/*/CMakeLists.txt:

Copy

target_link_libraries(YourPackage_YourLibraryName
     # ... existing libraries, if any ...
     Findlib::lwt)

Click your IDE's Build button

Not using DkSDK?

FIRST, do one or all of the following:

Run:
Copy
```
opam install lwt.5.6.1
```

Edit your dune-project and add:

Copy

(package
  (name YourExistingPackage)
  (depends
  ; ... existing dependenices ...
  (lwt (>= 5.6.1))))

Then run:

Copy

dune build *.opam # if this fails, run: dune build

Edit your <package>.opam file and add:

Copy

depends: [
  # ... existing dependencies ...
  "lwt" {>= "5.6.1"}
]

Then run:

Copy

opam install . --deps-only

FINALLY, add the lwt library to any desired (library)and/or (executable) targets in your **/dune files:

Copy

(library
  (name YourLibrary)
  ; ... existing library options ...
  (libraries
    ; ... existing libraries ...
    lwt))

(executable
  (name YourExecutable)
  ; ... existing executable options ...
  (libraries
    ; ... existing libraries ...
    lwt))

Parameters

module Ord:OrderedType

Signature

typeelt`` =Ord.t

Type of elements contained in the priority queue.

type t

Type of priority queues.

valempty :t

The empty priority queue. Contains no elements.

valis_empty :t -> bool

is_empty q evaluates to true iff q is empty.

valadd :elt -> t -> t

add e q evaluates to a new priority queue, which contains all the elements of q, and the additional element e.

valunion :t -> t -> t

union q q' evaluates to a new priority queue, which contains all the elements of both q and q'.

valfind_min :t -> elt

find_min q evaluates to the minimum element of q if it is not empty, and raises Not_found otherwise.

vallookup_min :t -> elt option

lookup_min q evaluates to Some e, where e is the minimum element of q, if q is not empty, and evaluates to None otherwise.

valremove_min :t -> t

remove_min q evaluates to a new priority queue, which contains all the elements of q except for its minimum element. Raises Not_found if q is empty.

valsize :t -> int

size q evaluates to the number of elements in q.
