Implementing Rust functions and calling them from Tcl scripts involves a multi-step process. Here's a high-level overview of how you can achieve this:
-
Writing Rust Code: Start by writing the desired functions in Rust. You'll need to compile this Rust code into a shared library (
.so
on Unix-like systems,.dll
on Windows). -
Creating a C Interface: Rust functions must be exposed with a C-compatible interface (using
extern "C"
), because most other languages including Tcl can easily interface with C code. -
Building a Shared Library: Compile your Rust project with
cargo
to create a shared library. Make sure to use the appropriate target for your operating system. -
Interfacing with Tcl: Tcl can interface with C code using the Foreign Function Interface (FFI) mechanism. You'll use the
load
command in Tcl to load the shared library.
