Code Serialization

val call : t Fmt.t

call fmt k outputs name () to fmt, where n is k's OCaml name.

val serialize : runtime_modname:string -> t Fmt.t

serialize ctx ppf k outputs the Cmdliner runes to parse command-line arguments represented by k at runtime.

type 'a arg = 'a Functoria.DSL.runtime_arg

The type for command-line arguments that reads a value of type 'a.

val create :
