lv2rs-core: Rust re-implementation of the LV2 core library.

This is a safe and idiomatic re-implementation of the LV2 core library. It goals are to provide an interface that is compatible with hosts written in C and uses an idiomatic API for plugin implementors.

Getting started

Creating a plugin binary is fairly simple: * Create a new library crate * Add the following entry to your Cargo.toml in order to build a dynamic library: [lib] crate-type = ["dylib"] * Add lv2rs-core as a dependency both in your Cargo.toml: [dependencies] lv2rs-core = "*" * Create a struct, implement Plugin for it, and use the lv2_main! macro to export the required symbols. For example: ``` extern crate lv2rs_core as core; use std::ffi::CStr;

struct MyPlugin {}

impl core::Plugin for MyPlugin { fn instantiate( descriptor: &core::Descriptor, _rate: f64, _bundlepath: &CStr, _features: Option> ) -> Self { Self {} }

unsafe fn connect_port(&mut self, port: u32, data: *mut ()) {}

fn run(&mut self, _n_samples: u32) {}

}

core::lv2_main!(core, MyPlugin, b"http://example.org/Dummy\0"); ```

That's it! Although, if you really want to get started with LV2, you should check out the tutorial at LV2's website.
