Methods from Deref<Target = AsciiChar>§

pub fn is_ascii_alphabetic(&self) -> bool

Check if the character is a letter (a-z, A-Z).

This method is identical to is_alphabetic()

pub fn is_ascii_digit(&self) -> bool

Check if the character is a number (0-9)

Examples

assert_eq!(AsciiChar::new('0').is_ascii_digit(), true);
assert_eq!(AsciiChar::new('9').is_ascii_digit(), true);
assert_eq!(AsciiChar::new('a').is_ascii_digit(), false);
assert_eq!(AsciiChar::new('A').is_ascii_digit(), false);
assert_eq!(AsciiChar::new('/').is_ascii_digit(), false);

pub fn is_ascii_alphanumeric(&self) -> bool

Check if the character is a letter or number

This method is identical to is_alphanumeric()

pub fn is_ascii_blank(&self) -> bool

Check if the character is a space or horizontal tab

Examples

assert!(AsciiChar::Space.is_ascii_blank());
assert!(AsciiChar::Tab.is_ascii_blank());
assert!(!AsciiChar::VT.is_ascii_blank());
assert!(!AsciiChar::LineFeed.is_ascii_blank());
assert!(!AsciiChar::CarriageReturn.is_ascii_blank());
assert!(!AsciiChar::FF.is_ascii_blank());

pub fn is_ascii_whitespace(&self) -> bool

Check if the character is a ’ ’, ‘\t’, ‘\n’, ‘\r’ or ‘\0xc’ (form feed).

This method is NOT identical to is_whitespace().

pub fn is_ascii_control(&self) -> bool

Check if the character is a control character

Examples

assert_eq!(AsciiChar::new('\0').is_ascii_control(), true);
assert_eq!(AsciiChar::new('n').is_ascii_control(), false);
assert_eq!(AsciiChar::new(' ').is_ascii_control(), false);
assert_eq!(AsciiChar::new('\n').is_ascii_control(), true);
assert_eq!(AsciiChar::new('\t').is_ascii_control(), true);
assert_eq!(AsciiChar::EOT.is_ascii_control(), true);

pub fn is_ascii_graphic(&self) -> bool

Checks if the character is printable (except space)

Examples

assert_eq!(AsciiChar::new('n').is_ascii_graphic(), true);
assert_eq!(AsciiChar::new(' ').is_ascii_graphic(), false);
assert_eq!(AsciiChar::new('\n').is_ascii_graphic(), false);

pub fn is_ascii_printable(&self) -> bool

Checks if the character is printable (including space)

Examples

assert_eq!(AsciiChar::new('n').is_ascii_printable(), true);
assert_eq!(AsciiChar::new(' ').is_ascii_printable(), true);
assert_eq!(AsciiChar::new('\n').is_ascii_printable(), false);

pub fn is_ascii_lowercase(&self) -> bool

Checks if the character is alphabetic and lowercase (a-z).

This method is identical to is_lowercase()

pub fn is_ascii_uppercase(&self) -> bool

Checks if the character is alphabetic and uppercase (A-Z).

This method is identical to is_uppercase()

pub fn is_ascii_punctuation(&self) -> bool

Checks if the character is punctuation

Examples

assert_eq!(AsciiChar::new('n').is_ascii_punctuation(), false);
assert_eq!(AsciiChar::new(' ').is_ascii_punctuation(), false);
assert_eq!(AsciiChar::new('_').is_ascii_punctuation(), true);
assert_eq!(AsciiChar::new('~').is_ascii_punctuation(), true);

pub fn is_ascii_hexdigit(&self) -> bool

Checks if the character is a valid hex digit

Examples

assert_eq!(AsciiChar::new('5').is_ascii_hexdigit(), true);
assert_eq!(AsciiChar::new('a').is_ascii_hexdigit(), true);
assert_eq!(AsciiChar::new('F').is_ascii_hexdigit(), true);
assert_eq!(AsciiChar::new('G').is_ascii_hexdigit(), false);
assert_eq!(AsciiChar::new(' ').is_ascii_hexdigit(), false);

pub fn make_ascii_uppercase(&mut self)

Replaces letters a to z with A to Z

pub fn make_ascii_lowercase(&mut self)

Replaces letters A to Z with a to z

pub fn to_ascii_uppercase(&self) -> AsciiChar

Maps letters a-z to A-Z and returns any other character unchanged.

Examples

assert_eq!(AsciiChar::new('u').to_ascii_uppercase().as_char(), 'U');
assert_eq!(AsciiChar::new('U').to_ascii_uppercase().as_char(), 'U');
assert_eq!(AsciiChar::new('2').to_ascii_uppercase().as_char(), '2');
assert_eq!(AsciiChar::new('=').to_ascii_uppercase().as_char(), '=');
assert_eq!(AsciiChar::new('[').to_ascii_uppercase().as_char(), '[');

pub fn to_ascii_lowercase(&self) -> AsciiChar

Maps letters A-Z to a-z and returns any other character unchanged.

Examples

assert_eq!(AsciiChar::new('U').to_ascii_lowercase().as_char(), 'u');
assert_eq!(AsciiChar::new('u').to_ascii_lowercase().as_char(), 'u');
assert_eq!(AsciiChar::new('2').to_ascii_lowercase().as_char(), '2');
assert_eq!(AsciiChar::new('^').to_ascii_lowercase().as_char(), '^');
assert_eq!(AsciiChar::new('\x7f').to_ascii_lowercase().as_char(), '\x7f');
