README

Uwt

Uwt provides OCaml bindings for libuv - on top of lwt.

  • Requests are translated to lwt-threads.

  • Callbacks that are called continually are most of the time not translated to the usual lwt semantic.

  • naming conventions mirror the conventions of libuv, so you can easily consult the official libuv manual. Only the differences are explained inside uwt.mli

  • Uwt is not compatible with lwt.unix. It's not a further Lwt_engine in addition to select and libev. However, the findlib package uwt.ext provides alternatives to the higher level modules of lwt.unix with a nearly identic interface (Uwt_io, Uwt_process, Uwt_log). You can also open the module Uwt_compat (package uwt.compat) that provides aliases with module names as found in lwt (e.g. Lwt_main instead of Uwt.Main). This is necessary, if you want to use the camlp4 syntax extension of lwt.

  • Uwt is not thread safe. All uwt functions should be called from your main thread.
