Struct Arg 

pub struct Arg { /* private fields */ }

An owned command-line argument token.

Implementations

impl Arg

pub fn new(value: impl Into<String>) -> Self

Creates an owned argument token.

pub fn as_str(&self) -> &str

Returns the borrowed token string.

pub fn into_string(self) -> String

Returns the owned token string.

pub fn is_option_separator(&self) -> bool

Returns whether this token is the -- option separator.

pub fn is_flag_like(&self) -> bool

Returns whether this token looks like a flag or option token.

pub fn is_positional(&self) -> bool

Returns whether this token looks positional.

Trait Implementations

impl AsRef<str> for Arg

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Arg

fn clone(&self) -> Arg

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Arg

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

Formats the value using the given formatter.

impl Display for Arg

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

Formats the value using the given formatter.

impl From<&str> for Arg

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<String> for Arg

fn from(value: String) -> Self

Converts to this type from the input type.

impl FromIterator<Arg> for RawArgs

fn from_iter<T: IntoIterator<Item = Arg>>(iter: T) -> Self

Creates a value from an iterator.

impl Hash for Arg

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Arg

fn eq(&self, other: &Arg) -> 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.
