:polyglot

All-in-one image for mixed-language pipelines. Inherits all :rust tools (which include all :core tools), and adds Deno and Python 3.

Base

FROM ghcr.io/driftsys/dock:rust (via build context)

Installed tools

Includes everything from :rust plus:

Use case: Deno FFI with Rust

The polyglot image supports Deno’s Foreign Function Interface (FFI) to call Rust-compiled shared libraries:

// Compile: cargo build --release --lib
const lib = Deno.dlopen("libmylib.so", {
  my_fn: { parameters: ["i32"], result: "i32" },
});
console.log(lib.symbols.my_fn(42));
lib.close();
