Struct ComparisonFunction

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

This enum specifies which comparison operator is used when texture comparison is enabled on this texture.

C++ enum: QOpenGLTexture::ComparisonFunction.

C++ documentation:

This enum specifies which comparison operator is used when texture comparison is enabled on this texture.

This enum was introduced or modified in Qt 5.5.

Implementations

Trait Implementations

impl Clone for ComparisonFunction

fn clone(&self) -> ComparisonFunction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ComparisonFunction

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

Formats the value using the given formatter.

impl From<ComparisonFunction> for c_int

fn from(value: ComparisonFunction) -> Self

Converts to this type from the input type.

impl From<i32> for ComparisonFunction

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for ComparisonFunction

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