Raml - Intelligent OCaml FFI in Rust
Direct OCaml bindings without ever leaving Rust - no C stubs!
(you still have to know how the C ffi bindings work; if you do, the macros are almost identical to the C ones in their naming and purpose)
Please see the example in examples
for the Rust code in rust
for the Rust code that OCaml code will call and the ocaml
directory for the OCaml code that calls the Rust code.
Also, please bear with me as I'm trying to add more documentation and examples, but I am very busy; if you see something, don't hesitate to add a PR or issue, thanks :)
A basic example demonstrates their usage:
caml!(ml_beef, |parameter|, <local>, {
let i = int_val!(parameter);
let res = 0xbeef * i;
println!("about to return 0x{:x} to OCaml runtime", res);
local = val_int!(res);
} -> local);
The macro takes care of automatically declaring CAMLparam
et. al, as well as CAMLlocal
and CAMLreturn
.
If you need more fine grained control, caml_body!
and others are available.

Usage
raml should work with a recent rustc
(I test on 1.16), and does not require nightly.
Add to your Cargo.toml
