.. but the test is kind of broken.. it appears that rust pads structs for alignment purposes? I can't get the struct to == 28.. that appears to be the native size of sockaddr_in6.. so we have a size 32 struct, for now.

Low-level bindings to the libuv library.
|
|
|
|
This module contains a set of direct, 'bare-metal' wrappers around
|
|
the libuv C-API.
|
|
|
|
Also contained herein are a set of rust records that map, in
|
|
approximate memory-size, to the libuv data structures. The record
|
|
implementations are adjusted, per-platform, to match their respective
|
|
representations.
|
|
|
|
There are also a collection of helper functions to ease interacting
|
|
with the low-level API (such as a function to return the latest
|
|
libuv error as a rust-formatted string).
|
|
|
|
As new functionality, existant in uv.h, is added to the rust stdlib,
|
|
the mappings should be added in this module.
|
|
|
|
This module's implementation will hopefully be, eventually, replaced
|
|
with per-platform, generated source files from rust-bindgen.
