Enum Arg 

pub enum Arg<'a> {
    DoubleDash,
    LongOption(&'a str),
    ShortOption(char),
    Value(&'a str),
}

Variants

DoubleDash

Used to represent --. After double dash all other args will always be ArgToken::Value

LongOption(&'a str)

Long option. Only name is stored (without --)

In get --config normal -f file -vs --config will be a long option with name config

ShortOption(char)

Short option. Only single ASCII char is stored (without -). UTF-8 here is not supported.

In get --config normal -f file -vs -f and -vs will be short options. v and s are treated as written separately (as ’-v -s`)

Value(&'a str)

Value of an option or an argument.

In get --config normal -v file normal and file will be a value

Trait Implementations

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.
