Struct SubCommand

pub struct SubCommand { /* private fields */ }

The abstract representation of a command line subcommand.

This struct describes all the valid options of the subcommand for the program. Subcommands are essentially “sub-Apps” and contain all the same possibilities (such as their own arguments, subcommands, and settings).

Examples

App::new("myprog")
    .subcommand(
        App::new("config")
            .about("Used for configuration")
            .arg(Arg::with_name("config_file")
                .help("The configuration file to use")
                .index(1)))
