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