Sourcemap processing in Python

This gist contains two Python modules:

sourcemap: a module to parse and generate JavaScript source maps
base64vlq: code to decode and encode base64 VLQ sequences, an encoding used in source maps.

Automatically set the correct source map for your Rust toolchain

When it comes to debugging Rust in VSCode, the CodeLLDB extension provides a great debugging experience. Until you try to step into some Rust stdlib code and are greeted with assembly.

Of course you can manually add a source map entry for your rust toolchain, which involves finding the current rustc version commit hash and the sysroot path for the source code:

$ rustc --version --verbose
rustc 1.76.0 (07dca489a 2024-02-04)
binary: rustc
