Enum Alpha 

pub enum Alpha {
    All,
    Dist,
    Lower,
    Upper,
    None,
}

Sets related to the alphabetic collating sequence

Variants

All

Both lower and upper case letters (“*”, “b”, “both”)

Dist

Characters that are easily distinguished (O,l,Z).

Lower

Lower case letters only (“l”, “lc”, “lower” or “lower-case”)

Upper

Upper case letters only (“u”, “uc”, “upper” or “upper-case”)

None

No letters

Trait Implementations

impl Clone for Alpha

fn clone(&self) -> Alpha

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CollatingSeq for Alpha

fn characters(&self) -> &[char]

return all characters from the charset

impl Debug for Alpha

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

Formats the value using the given formatter.

impl FromStr for Alpha

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Alpha

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 Alpha

fn eq(&self, other: &Alpha) -> 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 Copy for Alpha

impl Eq for Alpha

impl StructuralPartialEq for Alpha
