ocaml-containers
================
A bunch of containers,written in different occasions. Not all
containers are properly tested (see `tests/` and `make tests`
if you have installed `OUnit`).
The design is mostly centered around polymorphism rather than functors. Such
structures comprise:
- `PHashtbl`, a polymorphic hashtable (with open addressing)
- `SplayTree`, a polymorphic splay heap implementation (not quite finished)
- `SplayMap`, a polymorphic functional map based on splay trees
- `Heap`, an imperative heap based on `SplayTree`
- `Graph`, a polymorphic imperative directed graph (on top of `PHashtbl`)
- `Hashset`, a polymorphic imperative set on top of `PHashtbl`
- `LazyGraph`, a lazy graph structure on arbitrary (hashable+eq) types, with
basic graph functions that work even on infinite graphs, and printing to DOT.
- `FQueue`, a purely functional queue structure
- `Heap`, a purely functional polymorphic heap
- `Bij`, a GADT-based bijection language used to serialize/deserialize your
data structures
Other structures are:
- `Univ`, a universal type encoding with affectation
- `Cache`, a low level memoization cache for unary and binary functions
- `PersistentHashtbl`, a semi-persistent hashtable (similar to
[persistent arrays](https://www.lri.fr/~filliatr/ftp/ocaml/ds/parray.ml.html))
- `Deque`, an imperative double ended FIFO (double-linked list)
- `Future`, a set of tools for preemptive threading, including a thread pool,
monadic futures, and MVars (concurrent boxes)
- `Vector`, a growable array (pure OCaml, no C; not tested)
- `FlatHashtbl`, a (deprecated) open addressing hashtable with
a functorial interface (replaced by PHashtbl)
## Use
You can either build and install the library (see `Build`), or just copy
files to your own project. The last solution has the benefits that you
don't have additional dependencies nor build complications (and it may enable
more inlining). I therefore recommand it for its simplicity.
If you have comments, requests, or bugfixes, please share them! :-)
## Build
There are no dependencies (`Sequence` is included).
The `Bij` module requires OCaml `>= 4.00`. Type:
$ make
To build and run tests (requires `oUnit`):
$ opam install oUnit
$ make tests
$ ./tests.native
To build the small benchmarking suite (requires `Bench`):
$ opam install bench
$ make bench
$ ./benchs.native
