restd is a re-implementation of various std features. It started out with
std::fmt (still my favorite part), then I had to remake the core of std::io
as well. In the future, I plan on implementing things like threads, file and
std{in,out,err}, and whatever strikes my fancy.
Well, sure, go ahead...! The eventual hope is that I'll be able to use it myself. While in 0.1.x there are zero guarantees, but once I publish on crates.io I'll begin (mostly) adhering to semver.
However, do be warned: this is not made to be particularly usable. I did my
best, but it's not always good enough. Some features still rely on std and may
always, and others may only be available on Unix (my native platform). PR's are
always welcome though!
