[][src]Struct structopt_flags::VerboseNoDef

pub struct VerboseNoDef { /* fields omitted */ }

This struct provides the --verbose cli option, without a predefined default

Multiple occurrences, will increase the verbosity level

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

use log::LevelFilter;
use structopt::StructOpt;
use structopt_flags::GetWithDefault; // to access get_log_level

#[derive(Debug, StructOpt)]
#[structopt( name = "verbose_no_def", about = "An example using verbose flag with no predefined default")]
struct Opt {
    #[structopt(flatten)]
    verbose: structopt_flags::VerboseNoDef,
}

fn main() {
    let opt = Opt::from_args();
    let filter_level = opt.verbose.get_with_default(LevelFilter::Off);
    // set log level
}
