Code you wrote [Part II]

All I've worked on tonight is this dumb raycaster: http://hastebin.com/iyerililov.rs

I screwed up the projection something awful and I have no idea how, but otherwise it sort of works.

To compile: Install a recent Rust+Cargo nightly, save this file http://hastebin.com/huyobaripa.toml as "Cargo.toml," put the Rust source in "src/ray.rs," and type "cargo run." It will automatically download and build the dependencies.

There are better ways, but that would involve a deeper changes. You might even be able to match on something like [true, ..], I haven't checked. I'm not fond of the drift it would create.

A fairer comparison:
$ rustc >/dev/null 2>&1 && echo yep || echo nope
yep
$ symta >/dev/null 2>&1 && echo yep || echo nope
nope
