Enum ArgKind 

pub enum ArgKind {
    Boolean,
    Integer,
    Number,
    String,
    StringList,
    IntegerList,
    Json,
}

What one argument accepts.

A reduction of JSON Schema to the shapes a command line has: everything else is passed as one JSON document, because a shell argument is text and pretending otherwise only moves the parse somewhere less helpful.

Variants

Boolean

A switch. Accepts --flag and --flag true, because callers write both and one of them erroring is a round trip spent on syntax.

Integer

Number

String

StringList

Repeatable, and comma-splittable when the items are scalars.

IntegerList

Json

An object or array of objects: one JSON document.
