Expand description
Transforms common types to a char for basic token parsing
Required methods
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
fn is_alphanum(self) -> bool
Tests that self is an alphabetic character or a decimal digit
fn is_dec_digit(self) -> bool
fn is_dec_digit(self) -> bool
Tests that self is a decimal digit
fn is_hex_digit(self) -> bool
fn is_hex_digit(self) -> bool
Tests that self is an hex digit
fn is_oct_digit(self) -> bool
fn is_oct_digit(self) -> bool
Tests that self is an octal digit
