Struct glib::char::UChar

pub struct UChar(pub c_uchar);

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.to_glib().

Methods

impl UChar

pub fn new(c: char) -> Option<UChar>

Creates a Some(UChar) if the given char is representable as an libc::c_uchar

Example

extern "C" fn have_a_byte(b: libc::c_uchar);

let a = Char::new('a').unwrap();
assert!(a.0 == 65);
have_a_byte(a.to_glib());

let not_representable = Char::new('☔');
assert!(not_representable.is_none());

Trait Implementations

impl Debug for UChar

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Copy for UChar

impl Clone for UChar

fn clone(&self) -> UChar

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Eq for UChar
