ark::core::PositionalRule
Defined in header “ark/core/argument_parser.hh”.
Represents a positional rule. These don’t have flags, can appear only once, but can take one or more arguments. They are parsed in order.
These are the rules that the command line options are parsed from, and are normally instantiated and managed by the ArgumentParser itself.
