Enum CharsetName 

pub enum CharsetName {
    AlphaLower,
    AlphaUpper,
    Numeric,
    Mathops,
    Prose,
    Delim,
    MiscSpecial,
    Alpha,
    Special,
}

Translation layer between chars (e.g. for cli flags) and the actual character sets.

Especially, you can do CharsetName::from::<char>(c). Translations are:

CharsetName	associated char	contained chars
AlphaLower	'L'	matching regex [a-z]
AlphaUpper	'U'	matching regex [A-Z]
Numeric	'N'	matching regex [0-9]
Mathops	'M'	+, -, *, /, =, <, >
Prose	'P'	., ,, :, ;, !, ?, ', ",
Delim	'D'	(, ), {, }, [, ]
MiscSpecial	'X'	#, @, $, %, &, `

For convenience, there are also some charsets built from the “atomic” charsets shown above:

CharsetName	associated char	Contained Charsets
Alpha	'A'	AlphaLower, AlphaUpper
Special	'S'	Mathops, Punct, Delim, Quote, Blank, MiscSpecial

Trait Implementations

impl AddAssign<CharsetName> for CharsetSpec

fn add_assign(&mut self, name: CharsetName)

Performs the += operation.

impl Debug for CharsetName

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

Formats the value using the given formatter.

impl PartialEq for CharsetName

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

impl SubAssign<CharsetName> for CharsetSpec

fn sub_assign(&mut self, name: CharsetName)

Performs the -= operation.

impl TryFrom<char> for CharsetName

type Error = Error

The type returned in the event of a conversion error.

fn try_from(c: char) -> Result<Self>

Performs the conversion.

impl StructuralPartialEq for CharsetName
