Struct Command 

pub struct Command {
    pub name: &'static str,
    pub about: &'static str,
    pub long_about: &'static str,
    pub after_help: &'static str,
    pub after_long_help: &'static str,
    pub items: &'static [Item],
    pub subcommands: &'static [Sub],
    pub subcommand_required: bool,
    pub help_flag: bool,
    pub help_short: bool,
    pub version: Option<&'static str>,
}

One command’s help: what it is, what it takes, what it contains.

Written by the derive, as Item and Sub are: fields are added as help learns to show more, so a hand-written one tracks the release.

Fields

name: &'static str

The command’s own name; empty for a root that leaves it to argv[0].

about: &'static str

First paragraph of the description.

long_about: &'static str

The whole description, for --help.

after_help: &'static str

Text after the lists, for -h.

after_long_help: &'static str

Text after the lists, for --help.

items: &'static [Item]

Flags and positionals, in declaration order.

subcommands: &'static [Sub]

Subcommands, in declaration order.

subcommand_required: bool

Whether a subcommand must be given.

help_flag: bool

Whether --help is supplied (not declared or disabled).

help_short: bool

Whether the supplied help flag has -h as well as --help.
