Struct ArgSpec

pub struct ArgSpec {
    pub name: String,
    pub kind: ArgKind,
    pub help: Option<String>,
    pub required: bool,
}

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

name: String

kind: ArgKind

Always ArgKind::Positional today. Kept as a discriminator so the JSON shape can grow new arg kinds later without renaming fields (see #215 for the design pass).

help: Option<String>

required: bool

true when the arg has no default and no Option<T> wrapper.
