| The Rust compiler 0.1 is unleashed | |
| Today Mozilla and the Rust community are releasing version 0.1 of the Rust compiler | |
| and associated tools. | |
| Rust is a strongly-typed systems programming language in the C family with a focus | |
| on memory safety and concurrency. This is the initial release of the compiler after | |
| a multi-year development cycle focusing on self-hosting, implementation of the major | |
| features, and solidifying the syntax. |

| Rust functions that can be called from C | |
| We have a lot of scenarios now where people creating bindings want to be able to provide a callback that a C function can call. The current solution is to write a native C function that uses some unspecified internal APIs to send a message back to Rust code. The ideal solution involves writing no C code. | |
| Here is a minimal solution for creating functions in Rust that can be called from C code. The gist is: 1) we have yet another kind of function declaration, 2) this function cannot be called from Rust code, 3) it's value can be taken as an opaque unsafe pointer, 4) it bakes in the stack switching magic and adapts from the C ABI to the Rust ABI. | |
| Declarations of C-to-Rust (crust) functions: | |
| ``` | |
| crust fn callback(a: *whatever) { |
