Rustic

This package is a fork of rust-mode

Differences with rust-mode:

• compilation popup
• multiline error parsing
• translation of ANSI control sequences through xterm-color
• async org babel
• custom compilation process
• rustfmt errors in a rust compilation mode
• automatic RLS configuration with eglot or lsp-mode
• cask for testing
• requires emacs 26
• etc.

Some basic commands:

• rustic-compile
• rustic-recompile
• rustic-format-buffer
• rustic-racer-describe
