Enum LaunchValueShape 

pub enum LaunchValueShape {
    Flag,
    Text,
}

What one launch argument consumes from argv.

The two shapes are what a parser actually distinguishes on the command line: an option that stands alone, and one that consumes the argv token after it. A value parser then narrows that token to an identity, a path, or a duration, which is decode-side narrowing rather than shape - exactly as a wire type’s try_from narrows what decodes without changing what is written.

Variants

Flag

The option stands alone and consumes nothing.

Text

The option consumes one argv token.
