Geting started

Add the crate to your project, adding this in Cargo.toml:

[dependencies]
structopt-flags = "0.1"

In your code, you can use one or more flags provided by this crate. For instance:

extern crate failure;
extern crate structopt_flags;
#[macro_use]
extern crate structopt;

use failure::Error;
use structopt::StructOpt;
use structopt_flags::LogLevel; // traits for flags that can provide a log level

#[derive(Debug, StructOpt)]
#[structopt(name = "verbose", about = "An example using verbose flag")]
struct Opt {
    #[structopt(flatten)]
    verbose: structopt_flags::Verbose,
}

fn main() -> Result<(), Error> {
    let opt = Opt::from_args();
	let _log_level = opt.verbose.get_level_filter();
	// set the log level of your preferred log crate
    Ok(())
}
