Trait xcb::BaseError

pub trait BaseError {
    const EXTENSION: Option<Extension>;
    const NUMBER: u32;

    unsafe fn from_raw(raw: *mut xcb_generic_error_t) -> Self;
    unsafe fn into_raw(self) -> *mut xcb_generic_error_t;
    fn as_raw(&self) -> *mut xcb_generic_error_t;
    fn as_slice(&self) -> &[u8];
}

A trait to designate base protocol errors.

The base errors follow the usual resolution idiom of error_code offset.

This should be completely transparent to the user, as ProtocolError is resolving all types of errors together.

Associated Constants

const EXTENSION: Option<Extension>

The extension associated to this error, or None for the main protocol

const NUMBER: u32

The number associated to this error

Required methods

unsafe fn from_raw(raw: *mut xcb_generic_error_t) -> Self

Build an error from a raw pointer

Safety

raw must be a valid pointer to the error, and be allocated with libc::malloc

unsafe fn into_raw(self) -> *mut xcb_generic_error_t

Convert the error into a raw pointer

Safety

returned value should be freed with libc::free to avoid memory leak, or used to build a new error

fn as_raw(&self) -> *mut xcb_generic_error_t

Obtain the error as a raw pointer

fn as_slice(&self) -> &[u8]

Access to the raw error data
