This places songbird, serenity, and twilight onto the same WS library, hopefully reducing the compile overhead for everyone.
Tested using `cargo make ready` and by running `examples/voice`.
Closes#129.
This PR adds support for the simd-json library whenever decoding or encoding JSON responses. This may be enabled independently of serenity and twilight support for SIMD acceleration.

This extensive PR rewrites the internal mixing logic of the driver to use symphonia for parsing and decoding audio data, and rubato to resample audio. Existing logic to decode DCA and Opus formats/data have been reworked as plugins for symphonia. The main benefit is that we no longer need to keep yt-dlp and ffmpeg processes alive, saving a lot of memory and CPU: all decoding can be done in Rust! In exchange, we now need to do a lot of the HTTP handling and resumption ourselves, but this is still a huge net positive.
`Input`s have been completely reworked such that all default (non-cached) sources are lazy by default, and are no longer covered by a special-case `Restartable`. These now span a gamut from a `Compose` (lazy), to a live source, to a fully `Parsed` source. As mixing is still sync, this includes adapters for `AsyncRead`/`AsyncSeek`, and HTTP streams.
`Track`s have been reworked so that they only contain initialisation state for each track. `TrackHandles` are only created once a `Track`/`Input` has been handed over to the driver, replacing `create_player` and related functions. `TrackHandle::action` now acts on a `View` of (im)mutable state, and can request seeks/readying via `Action`.
Per-track event handling has also been improved -- we can now determine and propagate the reason behind individual track errors due to the new backend. Some `TrackHandle` commands (seek etc.) benefit from this, and now use internal callbacks to signal completion.
Due to associated PRs on felixmcfelix/songbird from avid testers, this includes general clippy tweaks, API additions, and other repo-wide cleanup. Thanks go out to the below co-authors.

This handles twilight's migration to a unified `Id` type, which is the only design change needing any handling on our part. All our `From`/`Into`s are covered now, and deprecated type aliases are no longer used.
This was tested using `cargo make ready` and by manually running "examples/twilight".
This PR adds support for twilight v0.8, mainly adapting to significant API changes introduced by v0.7. As a result of these, twilight no longer accepts arbitrary JSON input, so it seemed sensible to adapt our `Shard` design to no longer require the same.
Adding to this, I've added in a trait to allow an arbitrary `Shard` to be installed, given only an implementation of a method to send a `VoiceStateUpdate`. Together, `Sharder::Generic` (songbird::shards::VoiceUpdate) and `Shard::Generic` (songbird::shards::GenericSharder) should allow any library to be hooked in to Songbird.
This PR was tested using `cargo make ready` and by manually testing `examples/twilight`.
Flume's latest patch version requires toe new Rust 2021 edition, which is at odds with the current MSRV. This was tested using `cargo msrv` on the default feature set.
Includes two more small changes too small to warrant PRs.
1. Removes the `shard_count` parameter from `Songbird::twilight` & `Songbird::twilight_from_config` since the cluster contains it.
2. Drops the `Arc` wrapper around `Songbird` to match against an upcoming twilight 0.7 change
This PR does the following:
* Changes both `Reader::Extension` and `Reader::ExtensionSeek` to use `symphonia::io::MediaSource`.
* Removes the `File` and `Vec` variants of readers, instead opting to provide a `from_file` and `from_memory` associated function to create readers from the `File` and `Cursor<Vec<u8>>` implementations of `MediaSource`.
* Removes the ReadSeek trait.
* Added a dependency on `symphonia_core`. This crate has no additional dependencies.
This commit undoes #64 (and bumps the library MSRV accordingly), and modifies #60 to match the new `Call` connection handling.
This was tested using `cargo make ready`, and rustc v1.49.0 on `examples/serenity/voice`.
This change fixes tasks hanging due to rare cases of messages being lost between full Discord reconnections by placing a configurable timeout on the `ConnectionInfo` responses. This is a companion fix to [serenity#1255](https://github.com/serenity-rs/serenity/pull/1255). To make this doable, `Config`s are now used by all versions of `Songbird`/`Call`, and relevant functions are added to simplify setup with configuration. These are now non-exhaustive, correcting an earlier oversight. For future extensibility, this PR moves the return type of `join`/`join_gateway` into a custom future (no longer leaking flume's `RecvFut` type).
Additionally, this fixes the Makefile's feature sets for driver/gateway-only compilation.
This is a breaking change in:
* the return types of `join`/`join_gateway`
* moving `crate::driver::Config` -> `crate::Config`,
* `Config` and `JoinError` becoming `#[non_breaking]`.
This was tested via `cargo make ready`, and by testing `examples/serenity/voice_receive` with various timeout settings.
This change increases the version of DiscoRTP, which fixes upstream issues in libpnet and allows additional RTCP types to be added over time without breaking semver. This is a breaking change for users explicitly matching on RTCP packet types, as DiscoRTP is exposed here.
This has been tested using `cargo make ready`.
The upstream crate `spinning_top` used newer elements of rustc's std in a patch release, unknowingly bumping its MSRV to 1.49.0. This patch reverts to the older, compatible, version.
This has been tested by manually building `examples/serenity/voice` using rustc v1.48.0.
Closes#62.
Updates to the latest async-tungstenite version. This was tested by `cargo make ready` and by testing driver/gateway function via `examples/serenity/voice_storage`.
Adds support to the library for tokio 0.2 backward-compatibility. This should hopefully benefit, and prevent lavalink-rs from being blocked on this feature.
These can be reached using, e.g., `gateway-tokio-02`, `driver-tokio-02`, `serenity-rustls-tokio-02`, and `serenity-native-tokio-02` features.
Naturally, this requires some jiggering about with features and the underlying CI, which has been taken care of. Twilight can't be handled in this way, as their last tokio 0.2 version uses the deprecated Discord Gateway v6.
This should make dropping `ChildContainer`s and their parent `Input`s safer in async contexts.
It seems like SIGINT is insufficient to make wait terminate, but SIGKILL suffices. This introduced a new problem, namely that we have to remember and wait on *every* pid we create. This should, hopefully, put the issue of zombie processes to bed for good.
Linux/Unix requires that processes be waited, which is unfortunate as Windows lets us abandon them to the murderous whims of the OS. This PR adds Unix-specific behaviour to send a SIGINT before waiting on the process, and adds an additional thread per call for asset disposal on all platforms.
Closes#38.
---
* Close processes by SIGINT and wait on Unix
This seems to remedy the Linux-specific zombie processes. Addition of
nix as a dependency *should* be fine on Windows, since I believe it
compiles to an empty crate.
* Dispose of Tracks on auxiliary thread
This adds a mechanism for the mixer threads to perform potentially expensive deallocation/cleanup outside of the main loop, preventing deadline misses etc. This should make misbehaving `wait`s a bit more friendly.
