Struct CommandSpec 

pub struct CommandSpec {
    pub name: &'static str,
    pub about: &'static str,
    pub aliases: &'static [&'static str],
    pub feature: Option<Feature>,
    pub short: Option<char>,
    pub long_about: Option<&'static str>,
}

Static descriptor of a Command.

Every field is 'static because commands are compile-time entities — runtime-generated subcommands are a separate (unimplemented) concern.

Construct with struct-update over CommandSpec::DEFAULT so new optional fields do not churn every literal:

static SPEC: CommandSpec = CommandSpec {
    name: "deploy",
    about: "Deploy the thing",
    ..CommandSpec::DEFAULT
};

Fields

name: &'static str

The subcommand name as it appears on the CLI (mytool deploy).

about: &'static str

One-line summary shown in --help.

aliases: &'static [&'static str]

Alternative names accepted on the CLI. Displayed in help text.

feature: Option<Feature>

If Some, the command is only visible when the runtime Features set has this feature enabled. Unconditional commands leave this None.

short: Option<char>

Single-character short-flag alias — mytool -d invokes the command like mytool deploy. None for most commands; set by rtb generate command --short.

long_about: Option<&'static str>

Long-form help shown in the command’s own --help. None falls back to about; set by rtb generate command --long.

Implementations

impl CommandSpec

pub const DEFAULT: CommandSpec

A zero-valued descriptor for struct-update construction — see the type docs. Only the fields that differ need be set at each call site, so adding a new optional field later touches no existing literal.
