> **Notice**: `vst-rs` is deprecated.
>
> This crate is no longer actively developed or maintained. VST 2 has been [officially discontinued](http://web.archive.org/web/20210727141622/https://www.steinberg.net/en/newsandevents/news/newsdetail/article/vst-2-coming-to-an-end-4727.html) and it is [no longer possible](https://forum.juce.com/t/steinberg-closing-down-vst2-for-good/27722/25) to acquire a license to distribute VST 2 products. It is highly recommended that you make use of other libraries for developing audio plugins and plugin hosts in Rust.
>
> If you're looking for a high-level, multi-format framework for developing plugins in Rust, consider using [NIH-plug](https://github.com/robbert-vdh/nih-plug/) or [`baseplug`](https://github.com/wrl/baseplug/). If you're looking for bindings to specific plugin APIs, consider using [`vst3-sys`](https://github.com/RustAudio/vst3-sys/), [`clap-sys`](https://github.com/glowcoil/clap-sys), [`lv2(-sys)`](https://github.com/RustAudio/rust-lv2), or [`auv2-sys`](https://github.com/glowcoil/auv2-sys). If, despite the above warnings, you still have a need to use the VST 2 API from Rust, consider using [`vst2-sys`](https://github.com/RustAudio/vst2-sys) or generating bindings from the original VST 2 SDK using [`bindgen`](https://github.com/rust-lang/rust-bindgen).
`vst-rs` is a library for creating VST2 plugins in the Rust programming language.
This library is a work in progress, and as such it does not yet implement all
functionality. It can create basic VST plugins without an editor interface.
**Note:** If you are upgrading from a version prior to 0.2.0, you will need to update
your plugin code to be compatible with the new, thread-safe plugin API. See the
[`transfer_and_smooth`](examples/transfer_and_smooth.rs) example for a guide on how
to port your plugin.
## Library Documentation
Documentation for **released** versions can be found [here](https://docs.rs/vst/).
Development documentation (current `master` branch) can be found [here](https://rustaudio.github.io/vst-rs/vst/).
## Crate
This crate is available on [crates.io](https://crates.io/crates/vst). If you prefer the bleeding-edge, you can also
include the crate directly from the official [Github repository](https://github.com/rustaudio/vst-rs).
```toml
# get from crates.io.
vst = "0.3"
```
```toml
# get directly from Github. This might be unstable!
vst = { git = "https://github.com/rustaudio/vst-rs" }
```
## Usage
To create a plugin, simply create a type which implements the `Plugin` trait. Then call the `plugin_main` macro, which will export the necessary functions and handle dealing with the rest of the API.
## Example Plugin
A simple plugin that bears no functionality. The provided `Cargo.toml` has a
`crate-type` directive which builds a dynamic library, usable by any VST host.
`src/lib.rs`
```rust
#[macro_use]
extern crate vst;
use vst::prelude::*;
struct BasicPlugin;
impl Plugin for BasicPlugin {
fn new(_host: HostCallback) -> Self {
BasicPlugin
}
fn get_info(&self) -> Info {
Info {
name: "Basic Plugin".to_string(),
unique_id: 1357, // Used by hosts to differentiate between plugins.
..Default::default()
}
}
}
plugin_main!(BasicPlugin); // Important!
```
`Cargo.toml`
```toml
[package]
name = "basic_vst"
version = "0.0.1"
authors = ["Author "]
[dependencies]
vst = { git = "https://github.com/rustaudio/vst-rs" }
[lib]
name = "basicvst"
crate-type = ["cdylib"]
```

#### Packaging on OS X
On OS X VST plugins are packaged inside loadable bundles.
To package your VST as a loadable bundle you may use the `osx_vst_bundler.sh` script this library provides.
Example:
```
./osx_vst_bundler.sh Plugin target/release/plugin.dylib
Creates a Plugin.vst bundle
```
