command-parser: 0.4.0

Upgrade Path

The MSRV is now Rust 1.49.

Create an Arguments instance via Arguments::new instead of using the From implementation.

When checking if a command is case-sensitive use CaseSensitivity::is_sensitive.

Changes

Remove From<&str> implementation for Arguments (#763 - @vivian).

Hide the unicase dependency by offering alternatives in the API:

• Add CaseSensitivity::is_sensitive to check if the command is case-sensitive
• Implement AsMut<str> for CaseSensitivity
• Commands now iterates over (&str, bool) instead of &CaseSensitivity
• CommandsMut now iterates over (&mut str, bool) instead of &mut CaseSensitivity

(#692 - @vivian).
