    // Required methods
    fn as_char(self) -> char;
    fn is_alpha(self) -> bool;
    fn is_alphanum(self) -> bool;
    fn is_dec_digit(self) -> bool;

Transforms common types to a char for basic token parsing

Required Methods

fn as_char(self) -> char

makes a char from self

fn is_alpha(self) -> bool

Tests that self is an alphabetic character

Warning: for &str it recognizes alphabetic characters outside of the 52 ASCII letters

fn is_alphanum(self) -> bool

Tests that self is an alphabetic character or a decimal digit

fn is_dec_digit(self) -> bool

Tests that self is a decimal digit

fn is_hex_digit(self) -> bool

Tests that self is an hex digit

fn is_oct_digit(self) -> bool

Tests that self is an octal digit

fn len(self) -> usize

Gets the len in bytes for self
