Struct Args 

pub struct Args { /* private fields */ }

The arguments after the verb.

Implementations

impl Args

pub fn new(items: impl IntoIterator<Item = impl Into<String>>) -> Self

pub fn flag(&mut self, name: &str) -> bool

Take --name if present.

pub fn value(&mut self, name: &str) -> Result<Option<String>, String>

Take --name VALUE or --name=VALUE.

pub fn number<T: FromStr>(&mut self, name: &str) -> Result<Option<T>, String>

Take --name N as a number.

pub fn positional(&mut self) -> Option<String>

Take the next positional (- counts as one: stdin). Take options first, so an option’s value is not mistaken for a positional.

pub fn into_raw(self) -> Vec<String>

Whatever was not taken, in the original order (a bare -- before the items that followed it), for a verb that parses its arguments itself.

pub fn finish(self) -> Result<(), String>

Everything was taken; otherwise the first leftover is an error.
