Struct Arg 

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

Implementations

impl<'a> Arg<'a>

pub fn new(name: &'a str) -> Self

pub fn has_name(&self, name: &'a str) -> bool

Is this string this argument’s name?

pub fn is_flag(&self) -> bool

Is this argument a flag or a name?

pub fn num_values(self, n: i32) -> Self

Set the number of values this argument accepts IF its a flag!

pub fn get_values(&self) -> Values<'a>

pub fn is_match(&self, slice_matches: &[&'a str]) -> bool

Test if this Arg could consume a list of values If this arg has already consumed arguments, it wont match A name must accept exactly one argument

pub fn consume<'b>(&mut self, values: &'b mut Values<'a>) -> bool

Takes an array of values and consumes data from them Returns true if did consume, returns false if did not consume

Trait Implementations

impl<'a> Clone for Arg<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Arg<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for Arg<'a>

fn eq(&self, other: &Arg<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
