Struct AlphaNum 

pub struct AlphaNum(/* private fields */);

Store an alpha numeric byte which can be used as a short option

Implementations

impl AlphaNum

pub fn new(a: u8) -> Result<Self, NonAlphaNumError>

Check that a can be used as a short

Trait Implementations

impl AsRef<str> for AlphaNum

fn as_ref(&self) -> &str

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

impl Clone for AlphaNum

fn clone(&self) -> AlphaNum

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AlphaNum

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

Formats the value using the given formatter.

impl Display for AlphaNum

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

Formats the value using the given formatter.

impl PartialEq for AlphaNum

fn eq(&self, other: &AlphaNum) -> 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<'a> TryFrom<&'a u8> for &'a AlphaNum

type Error = NonAlphaNumError

The type returned in the event of a conversion error.

fn try_from(value: &'a u8) -> Result<Self, Self::Error>

Performs the conversion.
