Module std::char
Character manipulation (char type, Unicode Scalar Value)
This module provides the Char 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..
Statics
