}Expand description
Transforms a token into a char for basic string parsing
Required Methods§
sourcefn as_char(self) -> char
fn as_char(self) -> char
Makes a char from self
Example
use winnow::stream::AsChar as _;
assert_eq!('a'.as_char(), 'a');
assert_eq!(u8::MAX.as_char(), std::char::from_u32(u8::MAX as u32).unwrap());sourcefn is_alpha(self) -> bool
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
sourcefn is_alphanum(self) -> bool
fn is_alphanum(self) -> bool
Tests that self is an alphabetic character or a decimal digit
sourcefn is_dec_digit(self) -> bool
fn is_dec_digit(self) -> bool
Tests that self is a decimal digit
sourcefn is_hex_digit(self) -> bool
fn is_hex_digit(self) -> bool
Tests that self is an hex digit
sourcefn is_oct_digit(self) -> bool
fn is_oct_digit(self) -> bool
Tests that self is an octal digit
sourcefn is_newline(self) -> bool
fn is_newline(self) -> bool
Tests if byte is ASCII newline: \n
