Module rustc_unicode::char
[−]
[src]
Character manipulation (char
`char` type, Unicode Scalar Value)
This module provides the CharExt
`CharExttrait, as well as its implementation for the primitive
` trait, as well as its
implementation for the primitive char
`char` type, in order to allow
basic character manipulation.
A char
`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
`charcan always be safely cast to a
` can always be safely cast to a u32
`u32; however the converse is not always true due to the above range limits and, as such, should be performed via the

however the converse is not always true due to the above range limits
and, as such, should be performed via the from_u32
`from_u32` function.
