Struct Tick 

pub struct Tick {
    now: Duration,
    predicted_dt: Option<Duration>,
}

The frame clock an easing is read against: when this frame is, and how long the next one is expected to take.

A host with a frame rate of its own states the prediction (Tick::predicting); one that knows only what time it is says Tick::at and whoever holds the previous tick fills it in (Tick::after).

Fields

now: Duration

predicted_dt: Option<Duration>

Implementations

impl Tick

pub const fn predicting(now: Duration, predicted_dt: Duration) -> Self

The clock as a host that knows how long its frames take states it.

pub const fn at(now: Duration) -> Self

The clock as a host that knows only the time states it.

pub fn after(self, previous: Self) -> Self

This tick with an unstated prediction taken from the interval since previous, which is what a host reading its own frame history would have predicted.

pub const fn now(self) -> Duration

pub const fn predicted_dt(self) -> Duration

How long the next frame is expected to take: what the host stated, or what Tick::after derived, and nothing on a tick that has neither.

Trait Implementations

impl Clone for Tick

fn clone(&self) -> Tick

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Tick

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Tick

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Tick

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

impl Serialize for Tick

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Tick

impl StructuralPartialEq for Tick
