Struct TransitionLibrary 

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

Provides factory methods for creating common transition types.

Implementations

impl TransitionLibrary

pub fn new() -> Result<Self>

Creates a new transition library.

pub fn accelerate_decelerate( &self, duration: f64, final_value: f64, acceleration_ratio: f64, deceleration_ratio: f64, ) -> Result<Transition>

Creates a transition that accelerates then decelerates.

duration is measured in seconds.

The sum of acceleration_ratio and deceleration_ratio must be <= 1.0.

pub fn linear(&self, duration: f64, final_value: f64) -> Result<Transition>

Creates a linear transition to the final value over duration seconds.

pub fn instantaneous(&self, final_value: f64) -> Result<Transition>

Creates an instantaneous transition that jumps to the final value.

Trait Implementations

impl Clone for TransitionLibrary

fn clone(&self) -> TransitionLibrary

Returns a duplicate of the value.

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

Performs copy-assignment from source.
