Attribute Macro entrypoint 

#[entrypoint]

Re-export the macro to annotate the entry point.

Each MEX function file has an entrypoint called mexFunction. This is a C FFI function, which, preferably, you do not want to write yourself.

Instead, rustmex provides the entrypoint macro; a macro to mark your Rust entrypoint with. For example:

use rustmex::prelude::*;

#[rustmex::entrypoint]
fn hello_world(lhs: Lhs, rhs: Rhs) -> rustmex::Result<()> {
	println!("Hello Matlab!");
	Ok(())
}
