Struct ArgumentParser

pub struct ArgumentParser<'src: 'run, 'run> { /* private fields */ }

The argument parser is responsible for grouping positional arguments into argument groups, which consist of a path to a recipe and its arguments.

Argument parsing is substantially complicated by the fact that recipe paths can be given on the command line as multiple arguments, i.e., “foo” “bar” baz“, or as a single “::”-separated argument.

Error messages produced by the argument parser should use the format of the recipe path as passed on the command line.

Additionally, if a recipe is specified with a “::”-separated path, extra components of that path after a valid recipe must not be used as arguments, whereas arguments after multiple argument path may be used as arguments. As an example, foo bar baz may refer to recipe foo::bar with argument baz, but foo::bar::baz is an error, since bar is a recipe, not a module.
