Struct Feature

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

This enum defines the OpenGL texture-related features that can be tested for.

C++ enum: QOpenGLTexture::Feature.

C++ documentation:

This enum defines the OpenGL texture-related features that can be tested for.

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

Trait Implementations

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

type Output = QFlags<Feature>

The resulting type after applying the | operator.

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

Performs the | operation.

impl Clone for Feature

fn clone(&self) -> Feature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Feature

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

Formats the value using the given formatter.

impl From<Feature> for QFlags<Feature>

fn from(value: Feature) -> Self

Converts to this type from the input type.

impl From<Feature> for c_int

fn from(value: Feature) -> Self

Converts to this type from the input type.

impl From<i32> for Feature

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for Feature

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