Module rustc_unicode::char

Character manipulation (char type, Unicode Scalar Value)

This module provides the CharExt trait, as well as its implementation for the primitive char type, in order to allow basic character manipulation.

A char actually represents a Unicode Scalar Value, as it can contain any Unicode code point except high-surrogate and low-surrogate code points.

As such, only values in the ranges [0x0,0xD7FF] and [0xE000,0x10FFFF] (inclusive) are allowed. A char can always be safely cast to a u32; however the converse is not always true due to the above range limits and, as such, should be performed via the from_u32 function.

Structs

EscapeDefault	An iterator over the characters that represent a char, escaped for maximum portability.
EscapeUnicode	An iterator over the characters that represent a char, as escaped by Rust's unicode escaping rules.
ToLowercase	An iterator over the lowercase mapping of a given character, returned from the to_lowercase method on characters.
ToUppercase	An iterator over the uppercase mapping of a given character, returned from the to_uppercase method on characters.

Constants

MAX	The highest valid code point
UNICODE_VERSION	[Unstable] The version of Unicode that the unicode parts of CharExt and UnicodeStrPrelude traits are based on.

Functions

from_digit	Converts a number to the character representing it.
from_u32	Converts a u32 to an Option<char>.
canonical_combining_class	[Deprecated]
compose	[Deprecated]
decompose_canonical	[Deprecated] Compute canonical Unicode decomposition for character
decompose_compatible	[Deprecated] Compute canonical or compatible Unicode decomposition for character
