Struct Arguments 

pub struct Arguments<'a> { /* private fields */ }

Stores the arguments of the parser.

Implementations

impl<'a> Arguments<'a>

pub fn single_value(&self, arg_name: &'static str) -> Option<&String>

Return the value of an argument if the argument exists and has the type String. Otherwise return None.

pub fn flag_present(&self, arg_name: &'static str) -> bool

Return whether an arg_name argument of type flag exists.

pub fn multiple_values(&self, arg_name: &'static str) -> Option<&[String]>

Return the value of an argument if the argument exists and has the type vector. Otherwise return None.

pub fn extra_args(&self) -> Vec<String>

Get the extra arguments (all arguments after --).

pub fn parse_from_cmdline(&mut self) -> Result<()>

Collect the command line arguments and the values provided for them.

pub fn parse(&mut self, args: &[String]) -> Result<()>

Clear split between the actual arguments of the process, the extra arguments if any and the --help and --version arguments if present.

Trait Implementations

impl<'a> Clone for Arguments<'a>

fn clone(&self) -> Arguments<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for Arguments<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> Default for Arguments<'a>

fn default() -> Arguments<'a>

Returns the “default value” for a type.
