Struct MotionPass 

pub struct MotionPass { /* private fields */ }

One directional pass of a Motion: a duration together with its easing curve.

A one-way motion needs one pass, which Motion::new creates for you. Use a MotionPass when the reverse leg of an alternating motion needs its own duration or easing, via Motion::with_reverse_pass. Local pass time advances from zero to one; the easing maps that time to presentation progress and may overshoot or be non-monotonic.

Examples

use gpui::{Motion, MotionPass, millis};

let motion = Motion::new(millis(500)).with_reverse_pass(MotionPass::new(millis(1000)));
assert_eq!(motion.forward_pass().duration(), millis(500));
assert_eq!(motion.reverse_pass().unwrap().duration(), millis(1000));

Implementations

impl MotionPass

pub fn new(duration: Duration) -> Self

Creates a linear pass of duration. A zero duration is valid.

pub fn with_easing(self, easing: impl Fn(f32) -> f32 + 'static) -> Self

Returns this pass with easing as its curve.

pub fn duration(&self) -> Duration

Returns the length of this pass.

See Motion for how a zero-length pass resolves.

pub fn easing(&self) -> &Easing

Returns the easing curve of this pass.

Trait Implementations

impl Clone for MotionPass

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl From<Duration> for MotionPass

fn from(duration: Duration) -> Self

Converts to this type from the input type.
