rust-ocaml-starter

An example project using ocaml-rs to link an OCaml library into a Rust program.

If you're looking for an example of calling into Rust from OCaml take a look at ocaml-rust-starter

New project checklist

• Update README.md
• Update the project name in dune-project
• Update the crate name in Cargo.toml
• Update lib/dune and lib/dune with the name of your project in place of rust_ocaml_starter/rust-ocaml-starter
• Rename rust-ocaml-starter.opam to match the name of your project
• Remove lib/rust_ocaml_starter.ml add your own OCaml files
• Edit src/lib.rs

Many of the renaming steps can be automated using init.sh:

$ ./init.sh my_project my-project

init.sh accepts two arguments: the name of the OCaml project and the public_name, if they are the same then one argument is acceptable.

NOTE: init.sh is destructive and can only be executed once (it will remove itself) - make sure you have no modifications that you want to keep before running init.sh.

Building

Optionally create a local OPAM switch (choose the version you prefer):

opam update
opam switch create . ocaml-base-compiler.4.14.0
eval $(opam env) && opam switch
opam install dune

Then:

cargo build

to run the program:

cargo run
