Both a "cargo update" and a bump of major versions of a few deps.
I left a few alone:
* base64 because some of the deps depend on 0.11 (and 0.9), so I don't
want to pull in a third version (0.12).
* ring because libpasta depends on this version and I don't want to pull
in two of them.
* time because it's not trivial. Last I checked, time 0.2 couldn't even
do what I wanted at all.
I also made tokio use parking_lot, since I pull it in anyway.
I'm getting deprecation warnings for std::sync::ONCE_INIT, and I'm
not sure when std::sync::Once::new() became a const fn. Just as easy to
switch to parking_lot.
This is mostly just "cargo fix --edition" + Cargo.toml changes.
There's one fix for upgrading to NLL in db/writer.rs:
Writer::previously_opened wouldn't build with NLL because of a
double-borrow the previous borrow checker somehow didn't catch.
Restructure to avoid it.
I'll put elective NLL changes in a following commit.
* the "lib: {}" print didn't do anything. It turns out that the pkg-config
crate emits the necessary metadata for linking automatically. I had the
wrong format and didn't notice because something else did it correctly.
* gcc::Config is deprecated; the new name is Build.
* and the crate is now called cc, version 1.0.
Stuff found while looking at #11. Still haven't figured that issue out.
This significantly improves safety of the ffmpeg interface. The complex
ABIs aren't accessed directly from Rust. Instead, I have a small C
wrapper which uses the ffmpeg C API and the C headers at compile-time to
determine the proper ABI in the same way any C program using ffmpeg
would, so that the ABI doesn't have to be duplicated in Rust code.
I've tested with ffmpeg 2.x and ffmpeg 3.x; it seems to work properly
with both where before ffmpeg 3.x caused segfaults.
It still depends on ABI compatibility between the compiled and running
versions. C programs need this, too, and normal shared library
versioning practices provide this guarantee. But log both versions on
startup for diagnosing problems with this.
