remove `hex` dependency in bootstrap First commit removes the `hex` dependency, as we can achieve the same output with the added function, which is very small and simple. Second commit creates a test module for the helpers util and adds unit tests for multiple helper functions, including `hex_encode`.
This directory contains some source code for the Rust project, including:
- The bootstrapping build system
- Various submodules for tools, like cargo, tidy, etc.
For more information on how various parts of the compiler work, see the rustc dev guide.
