Struct UChar

pub struct UChar(pub u8);

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());

Trait Implementations

impl Clone for UChar

fn clone(&self) -> UChar

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UChar

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<UChar> for char

fn from(c: UChar) -> char

Converts to this type from the input type.

impl From<UChar> for u8

fn from(c: UChar) -> u8

Converts to this type from the input type.

impl From<u8> for UChar

fn from(c: u8) -> UChar

Converts to this type from the input type.

impl PartialEq for UChar

fn eq(&self, other: &UChar) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<char> for UChar

type Error = TryFromIntError

The type returned in the event of a conversion error.

fn try_from(c: char) -> Result<UChar, <UChar as TryFrom<char>>::Error>

Performs the conversion.
