Struct qt_gui::q_opengl_functions::OpenGLFeature

pub struct OpenGLFeature(/* private fields */);

This enum defines OpenGL and OpenGL ES features whose presence may depend on the implementation.

C++ enum: QOpenGLFunctions::OpenGLFeature.

C++ documentation:

This enum defines OpenGL and OpenGL ES features whose presence may depend on the implementation.

The OpenGLFeatures type is a typedef for QFlags<OpenGLFeature>. It stores an OR combination of OpenGLFeature values.

Trait Implementations

impl<T: Into<QFlags<OpenGLFeature>>> BitOr<T> for OpenGLFeature

type Output = QFlags<OpenGLFeature>

The resulting type after applying the | operator.

fn bitor(self, rhs: T) -> QFlags<OpenGLFeature>

Performs the | operation.

impl Clone for OpenGLFeature

fn clone(&self) -> OpenGLFeature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OpenGLFeature

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

Formats the value using the given formatter.

impl From<OpenGLFeature> for QFlags<OpenGLFeature>

fn from(value: OpenGLFeature) -> Self

Converts to this type from the input type.

impl From<OpenGLFeature> for c_int

fn from(value: OpenGLFeature) -> Self

Converts to this type from the input type.

impl From<i32> for OpenGLFeature

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for OpenGLFeature

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

This method tests for self and other values to be equal, and is used by ==.

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

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