Enum ArgKind 

#[non_exhaustive]
pub enum ArgKind {
    Positional,
}

What kind of positional argument an ArgSpec describes.

Currently every entry is Positional; the typed enum reserves space for future variants (e.g. Stdin markers) without breaking existing JSON consumers. Serialises as "positional".

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Positional

A required-or-optional positional argument on the subcommand.
