Rust bindings - median

Still a work in progress so, use at your own risk, but here is some Rust code that exposes the max-sdk as a rust -sys library and also adds some higher level constructs for creating externals and interacting with the sdk.

https://github.com/Cycling74/median/tree/develop/median

Here is a very basic code example, implementing a Max external.

use median::{
    atom::Atom, builder::MaxWrappedBuilder, max_sys::t_atom_long, object::MaxObj, post,
    symbol::SymbolRef, wrapper::*,
};

median::external! {
    pub struct Example;

    impl MaxObjWrapped<Example> for Example {
        fn new(builder: &mut dyn MaxWrappedBuilder<Self>) -> Self {
            let _ = builder.add_inlet(median::inlet::MaxInlet::Proxy);
            Self
        }
    }

    impl Example {
        #[bang]
        pub fn bang(&self) {
            let i = median::inlet::Proxy::get_inlet(self.max_obj());
            median::object_post!(self.max_obj(), "bang from inlet {}", i);
        }

        #[int]
        pub fn int(&self, v: t_atom_long) {
            let i = median::inlet::Proxy::get_inlet(self.max_obj());
            post!("int {} from inlet {}", v, i);
        }

        #[list]
        pub fn list(&self, atoms: &[Atom]) {
            post!("got list with length {}", atoms.len());
        }

        #[any]
        pub fn baz(&self, sel: &SymbolRef, atoms: &[Atom]) {
            post!("got any with sel {} and length {}", sel, atoms.len());
        }
    }
}
