Easily add a --verbose flag to CLIs using Structopt
extern crate clap_verbosity_flag;
// ...
#[derive(Debug, StructOpt)]
struct Cli {
#[structopt(flatten)]
verbose: clap_verbosity_flag::Verbosity,
}By default, it'll only report errors.
Passing -v one time also prints warnings,
-vv enables info logging,
-vvv debug,
and -vvvv trace.
