Rex Proc Macros (rexlang-proc-macro)

This crate provides procedural macros for bridging Rust types and Rex values.

#[derive(Rex)]

The derive generates:

• an ADT declaration suitable for injection into an Engine
• IntoPointer / FromPointer implementations to convert between Rust values and Rex runtime values

The generated code now targets the public rexlang crate path, so embedders only need rexlang instead of rexlang-core.
