Enum Token 

pub enum Token<'a> {
    Flag(Flag<'a>),
    Value(&'a str),
}

Defines a Token that has been read from the command line.

Variants

Flag(Flag<'a>)

Flag.

Value(&'a str)

Value (i.e. everything that is not a short or long flag).

Implementations

impl<'a> Token<'a>

pub fn is_short_flag(input: &str) -> bool

Evaluate if the token string is a short flag.

pub fn as_short_flag(input: &str) -> Option<Self>

Evaluate if the token string is a short flag, and then return it.

pub fn is_long_flag(input: &str) -> bool

Evaluate if the token string is a long flag.

pub fn as_long_flag(input: &'a str) -> Option<Self>

Evaluate if the token string is a long flag, and then return it.

pub fn is_flag(input: &str) -> bool

Evaluate if the token string is a flag.

pub fn is_number(input: &str) -> bool

Evaluate if the token string represents a number.

pub fn tokenize(input: &'a str) -> Self

Convert a input string into a token.

Trait Implementations

impl<'a> Clone for Token<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Token<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for Token<'a>

fn eq(&self, other: &Token<'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.
