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.
