Struct CmdArg 

pub struct CmdArg<I = String> {
    pub opts: Vec<(String, Ast<I>)>,
    pub arg: Ast<I>,
}

One command-application argument (3b-β): arg is the ordinary positional argument value, opts is this argument’s supplied ?(l = e, …) labeled-optional bundle — upstream’s UTCommandArg of (label * expr) list * expr (types.cppo.ml:583-584). All of 0.0.6, and every V0_1 command call with no bundle, emits opts: vec![], behaving exactly like a bare Ast. A non-empty opts folds through eval::Interp::apply_with_opts (like Ast::ApplyOpt) instead of a plain apply; each label the command declares but this call omits still defaults to None there.

Fields

opts: Vec<(String, Ast<I>)>

arg: Ast<I>
