Struct glib::char::UChar[−][src]

pub struct UChar(pub c_uchar);

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());
