rsed - A very rusty sed implementation

This application is a very naive implementation of sed done using Rust. This is just an exercise to practice and learn rust, so I don't expect it to be nearly as powerful as sed.

Implemented features

• Substitution with the g, p and, c and w commands
• Range by number and/or regular expressions
• -n, -f and -e flags
• Line insertion with the a and i commands.
• Still doesn't handle escaped characters.
• The d, q, s, ! and = commands are also implemented.
