pub struct SubCommand<'a> { /* private fields */ }
Expand description
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-App
s” and contain all the same possibilities (such as their own
arguments, subcommands, and settings).
§Examples
App::new("myprog")
.subcommand(
SubCommand::with_name("config")
.about("Used for configuration")
.arg(Arg::with_name("config_file")
.help("The configuration file to use")
.index(1)))
