Enum WinsysID 

#[non_exhaustive]
pub enum WinsysID {
    Any,
    Stub,
    Glx,
    EglXlib,
    EglNull,
    EglGdl,
    EglWayland,
    EglKms,
    EglAndroid,
    EglMir,
    Wgl,
    Sdl,
}

Identifies specific window system backends that Cogl supports.

These can be used to query what backend Cogl is using or to try and explicitly select a backend to use.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Any

Implies no preference for which backend is used

Stub

Use the no-op stub backend

Glx

Use the GLX window system binding API

EglXlib

Use EGL with the X window system via XLib

EglNull

Use EGL with the PowerVR NULL window system

EglGdl

Use EGL with the GDL platform

EglWayland

Use EGL with the Wayland window system

EglKms

Use EGL with the KMS platform

EglAndroid

Use EGL with the Android platform

EglMir

Use EGL with the Mir server

Wgl

Use the Microsoft Windows WGL binding API

Sdl

Use the SDL window system

Trait Implementations

impl Clone for WinsysID

fn clone(&self) -> WinsysID

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WinsysID

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

Formats the value using the given formatter.

impl Display for WinsysID

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

Formats the value using the given formatter.

impl Hash for WinsysID

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 Ord for WinsysID

fn cmp(&self, other: &WinsysID) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for WinsysID

fn eq(&self, other: &WinsysID) -> 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 PartialOrd for WinsysID

fn partial_cmp(&self, other: &WinsysID) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
