Struct raw_window_handle::unix::XlibDisplayHandle

#[non_exhaustive]
pub struct XlibDisplayHandle {
    pub display: Option<NonNull<c_void>>,
    pub screen: c_int,
}

Raw display handle for Xlib.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

display: Option<NonNull<c_void>>

A pointer to an Xlib Display.

It is strongly recommended to set this value, however it may be set to None to request the default display when using EGL.

screen: c_int

An X11 screen to use with this display handle.

Note, that X11 could have multiple screens, however graphics APIs could work only with one screen at the time, given that multiple screens usually reside on different GPUs.

Implementations

impl XlibDisplayHandle

pub fn new(display: Option<NonNull<c_void>>, screen: c_int) -> Self

Create a new handle to a display.

Example

let display: NonNull<c_void>;
let screen;
let handle = XlibDisplayHandle::new(Some(display), screen);

Trait Implementations

impl Clone for XlibDisplayHandle

fn clone(&self) -> XlibDisplayHandle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for XlibDisplayHandle

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

Formats the value using the given formatter.

impl From<XlibDisplayHandle> for RawDisplayHandle

fn from(value: XlibDisplayHandle) -> Self

Converts to this type from the input type.

impl Hash for XlibDisplayHandle

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for XlibDisplayHandle

fn eq(&self, other: &XlibDisplayHandle) -> 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.
