Crate fyi_msg

FYI Msg

This crate contains the objects providing the heart of the FYI command line application, namely Msg, a simple struct for status-like messages that can be easily printed to STDOUT or STDERR.

Examples

use fyi_msg::{Msg, MsgKind};

// One way.
Msg::new(MsgKind::Success, "You did it!")
    .with_newline(true)
    .print();

// Another equivalent way.
Msg::success("You did it!").print();

For more usage examples, check out the examples/msg demo, which covers just about every common use case.
