Struct qt_gui::q_static_text::PerformanceHint

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

This enum the different performance hints that can be set on the QStaticText. These hints can be used to indicate that the QStaticText should use additional caches, if possible, to improve performance at the expense of memory. In particular, setting the performance hint AggressiveCaching on the QStaticText will improve performance when using the OpenGL graphics system or when drawing to a QOpenGLWidget.

C++ enum: QStaticText::PerformanceHint.

Implementations

impl PerformanceHint

pub fn to_int(&self) -> c_int

impl PerformanceHint

pub const ModerateCaching: PerformanceHint = _

Do basic caching for high performance at a low memory cost. (C++ enum variant: ModerateCaching = 0)

pub const AggressiveCaching: PerformanceHint = _

Use additional caching when available. This may improve performance at a higher memory cost. (C++ enum variant: AggressiveCaching = 1)

Trait Implementations

impl Clone for PerformanceHint

fn clone(&self) -> PerformanceHint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PerformanceHint

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

Formats the value using the given formatter.

impl From<PerformanceHint> for c_int

fn from(value: PerformanceHint) -> Self

Converts to this type from the input type.

impl From<i32> for PerformanceHint

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for PerformanceHint

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