Struct LongFlag 

pub struct LongFlag { /* private fields */ }

A long flag name such as verbose for --verbose.

Implementations

impl LongFlag

pub fn new(name: impl Into<String>) -> Result<Self, FlagNameError>

Creates a long flag from a validated name without the leading --.

Errors

Returns FlagNameError::InvalidLongFlagName when name is not a basic long flag name.

pub fn as_str(&self) -> &str

Returns the long flag name without the leading --.

pub fn to_token(&self) -> String

Returns the token form, such as --verbose.

Trait Implementations

impl AsRef<str> for LongFlag

fn as_ref(&self) -> &str

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

impl Clone for LongFlag

fn clone(&self) -> LongFlag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LongFlag

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

Formats the value using the given formatter.

impl Display for LongFlag

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

Formats the value using the given formatter.

impl Hash for LongFlag

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 LongFlag

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