Struct MotionSpec 

pub struct MotionSpec {
    pub enter: Pace,
    pub exit: Pace,
    pub reduced: Reduced,
    pub shortcut: Shortcut,
}

The timing of one named motion.

Fields

enter: Pace

Toward the shown / opened / new state.

exit: Pace

Back toward the hidden / closed / old state. Exits are shorter.

reduced: Reduced

shortcut: Shortcut

Implementations

impl MotionSpec

pub fn timing( self, direction: Direction, motion: EffectiveMotion, source: MotionSource, ) -> Timing

How this motion moves in direction, for the motion the person allows and what started it.

pub fn timing_over( self, direction: Direction, motion: EffectiveMotion, source: MotionSource, stretch: f64, ) -> Timing

Self::timing for a travel stretch times the motion’s reference distance: longer travel takes longer, by the square root of the ratio, never past slow. Material’s rule: a short hop and a cross-screen move at one speed read as one too slow or the other too fast.

impl MotionSpec

pub fn progress_after( self, direction: Direction, motion: EffectiveMotion, source: MotionSource, elapsed: Duration, ) -> f64

The progress (0..=1) of this motion run once from rest, elapsed after it started: for a motion fixed to a known instant that keeps no state of its own (a banner arriving from when it first showed).

pub fn eased(self, motion: EffectiveMotion, fraction: f64) -> f64

This motion’s entrance curve at fraction (0..=1) of its run, for a driver that keeps its own linear clock (the overview’s, which credits time a full presenter held it): the same shape a run from rest has.

pub fn settle_time( self, direction: Direction, motion: EffectiveMotion, source: MotionSource, ) -> Duration

How long this motion run once from rest takes to settle; zero when it lands at once.

Trait Implementations

impl Clone for MotionSpec

fn clone(&self) -> MotionSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MotionSpec

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

Formats the value using the given formatter.

impl PartialEq for MotionSpec

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