pub struct UChar(pub u8);
Expand description
Wrapper for values where C functions expect a plain C unsigned char
This UChar
type is a wrapper over an libc::c_uchar
, so that we can pass it to Glib or C functions.
The check for whether a Rust char
(a Unicode scalar value) actually fits in a libc::c_uchar
is
done in the new
function; see its documentation for details.
The inner libc::c_uchar
(which is equivalent to u8
) can be extracted with .0
, or
by calling my_char.into_glib()
.
Examples
use glib::UChar;
use std::convert::TryFrom;
UChar::from(b'a');
UChar::try_from('a').unwrap();
assert!(UChar::try_from('☔').is_err());
ⓘ
extern "C" fn have_a_byte(b: libc::c_uchar);
have_a_byte(UChar::from(b'a').into_glib());
