Struct qt_core::TimerType

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

The timer type indicates how accurate a timer can be.

C++ enum: Qt::TimerType.

C++ documentation:

The timer type indicates how accurate a timer can be.

On UNIX (including Linux, macOS, and iOS), Qt will keep millisecond accuracy for Qt::PreciseTimer. For Qt::CoarseTimer, the interval will be adjusted up to 5% to align the timer with other timers that are expected to fire at or around the same time. The objective is to make most timers wake up at the same time, thereby reducing CPU wakeups and power consumption.

On Windows, Qt will use Windows's Multimedia timer facility (if available) for Qt::PreciseTimer and normal Windows timers for Qt::CoarseTimer and Qt::VeryCoarseTimer.

On all platforms, the interval for Qt::VeryCoarseTimer is rounded to the nearest full second (e.g. an interval of 23500ms will be rounded to 24000ms, and 20300ms to 20000ms).

Implementations

impl TimerType

pub fn to_int(&self) -> c_int

impl TimerType

pub const PreciseTimer: TimerType = _

Precise timers try to keep millisecond accuracy (C++ enum variant: PreciseTimer = 0)

pub const CoarseTimer: TimerType = _

Coarse timers try to keep accuracy within 5% of the desired interval (C++ enum variant: CoarseTimer = 1)

pub const VeryCoarseTimer: TimerType = _

Very coarse timers only keep full second accuracy (C++ enum variant: VeryCoarseTimer = 2)

Trait Implementations

impl Clone for TimerType

fn clone(&self) -> TimerType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TimerType

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

Formats the value using the given formatter.

impl From<TimerType> for c_int

fn from(value: TimerType) -> Self

Converts to this type from the input type.

impl From<i32> for TimerType

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for TimerType

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