Utilities for the char primitive type.
See also the char primitive type.
The char type represents a single character. More specifically, since
‘character’ isn’t a well-defined concept in Unicode, char is a ‘Unicode
scalar value’, which is similar to, but not the same as, a ‘Unicode code
point’.
This module exists for technical reasons, the primary documentation for
char is directly on the char primitive type itself.
This module is the home of the iterator implementations for the iterators
implemented on char, as well as some useful constants and conversion
functions that convert various types to char.
Re-exports§
pub use self::methods::encode_utf16_raw;Experimental pub use self::methods::encode_utf8_raw;Experimental
Structs§
- An iterator that decodes UTF-16 encoded code points from an iterator of
u16s. - An error that can be returned when decoding UTF-16 code points.
- An iterator that yields the literal escape code of a
char. - An iterator that yields the literal escape code of a
char. - Returns an iterator that yields the hexadecimal Unicode escape of a character, as
chars. - An error which can be returned when parsing a char.
- Returns an iterator that yields the lowercase equivalent of a
char. - Returns an iterator that yields the uppercase equivalent of a
char. - The error type returned when a checked char conversion fails.
Constants§
U+FFFD REPLACEMENT CHARACTER(�) is used in Unicode to represent a decoding error. Usechar::REPLACEMENT_CHARACTERinstead.- The version of Unicode that the Unicode parts of
charandstrmethods are based on. Usechar::UNICODE_VERSIONinstead.
Functions§
- Creates an iterator over the UTF-16 encoded code points in
iter, returning unpaired surrogates asErrs. Usechar::decode_utf16instead. - Converts a digit in the given radix to a
char. Usechar::from_digitinstead.
