Function decompose_canonical

fn decompose_canonical(c: char, f: &fn(char))

Returns the canonical decompostion of a character

Function decompose_compatible

fn decompose_compatible(c: char, f: &fn(char))

Returns the compatibility decompostion of a character

Function escape_default

fn escape_default(c: char, f: &fn(char))

Return a 'default' ASCII and C++11-like char-literal escape of a char.

The default is chosen with a bias toward producing literals that are legal in a variety of languages, including C++11 and similar C-family languages. The exact rules are:

• Tab, CR and LF are escaped as '\t', '\r' and '\n' respectively.
• Single-quote, double-quote and backslash chars are backslash-escaped.
• Any other chars in the range [0x20,0x7e] are not escaped.
• Any other chars are given hex unicode escapes; see escape_unicode.

Function escape_unicode

fn escape_unicode(c: char, f: &fn(char))

Return the hexadecimal unicode escape of a char.

The rules are as follows:

• chars in [0,0xff] get 2-digit escapes: \\\\xNN
• chars in [0x100,0xffff] get 4-digit escapes: \\\\uNNNN
• chars above 0x10000 get 8-digit escapes: \\\\UNNNNNNNN

Function from_digit

fn from_digit(num: uint, radix: uint) -> Option<char>

Converts a number to the character representing it.

Function from_u32

fn from_u32(i: u32) -> Option<char>

Convert from u32 to a character.

Function is_XID_continue

fn is_XID_continue(c: char) -> bool

Function is_XID_start

fn is_XID_start(c: char) -> bool

Function is_alphabetic

fn is_alphabetic(c: char) -> bool

Returns whether the specified character is considered a unicode alphabetic character

Function is_alphanumeric

fn is_alphanumeric(c: char) -> bool

Indicates whether a character is alphanumeric. Alphanumericness is defined in terms of the Unicode General Categories 'Nd', 'Nl', 'No' and the Derived Core Property 'Alphabetic'.

Function is_digit

fn is_digit(c: char) -> bool

Indicates whether the character is numeric (Nd, Nl, or No)

Function is_digit_radix

fn is_digit_radix(c: char, radix: uint) -> bool

Checks if a character parses as a numeric digit in the given radix. Compared to is_digit(), this function only recognizes the characters 0-9, a-z and A-Z.

Function is_lowercase

fn is_lowercase(c: char) -> bool

Indicates whether a character is in lower case, defined in terms of the Unicode General Category 'Ll'

Function is_uppercase

fn is_uppercase(c: char) -> bool

Indicates whether a character is in upper case, defined in terms of the Unicode General Category 'Lu'.

Function is_whitespace

fn is_whitespace(c: char) -> bool

Indicates whether a character is whitespace. Whitespace is defined in terms of the Unicode General Categories 'Zs', 'Zl', 'Zp' additional 'Cc'-category control codes in the range [0x09, 0x0d]

Function len_utf8_bytes

fn len_utf8_bytes(c: char) -> uint

Returns the amount of bytes this character would need if encoded in utf8

Function to_digit

fn to_digit(c: char, radix: uint) -> Option<uint>

Convert a char to the corresponding digit.
