* Low-level bindings to the libuv library.
*
* This module contains a set of direct, 'bare-metal' wrappers around
* the libuv C-API.
*
* We're not bothering yet to redefine uv's structs as Rust structs
* because they are quite large and change often between versions.
* The maintenance burden is just too high. Instead we use the uv's
* `uv_handle_size` and `uv_req_size` to find the correct size of the
* structs and allocate them on the heap. This can be revisited later.
*
* There are also a collection of helper functions to ease interacting
* with the low-level API.
*
* As new functionality, existent in uv.h, is added to the rust stdlib,
* the mappings should be added in this module.
