Struct GetterFromHistory 

pub struct GetterFromHistory<'a, G, TG: TimeGetter<E>, E: Copy + Debug> { /* private fields */ }

As histories return values at times, we can ask them to return values at the time of now or now with a delta. This makes that much easier and is the recommended way of following MotionProfiles.

Implementations

impl<'a, G, TG: TimeGetter<E>, E: Copy + Debug> GetterFromHistory<'a, G, TG, E>

pub fn new_no_delta( history: &'a mut impl History<G, E>, time_getter: Reference<TG>, ) -> Self

Constructor such that the time in the request to the history will be directly that returned from the TimeGetter with no delta.

pub fn new_start_at_zero( history: &'a mut impl History<G, E>, time_getter: Reference<TG>, ) -> Result<Self, Error<E>>

Constructor such that the times requested from the History will begin at zero where zero is the moment this constructor is called.

pub fn new_custom_start( history: &'a mut impl History<G, E>, time_getter: Reference<TG>, start: Time, ) -> Result<Self, Error<E>>

Constructor such that the times requested from the History will start at a given time with that time defined as the moment of construction.

pub fn new_custom_delta( history: &'a mut impl History<G, E>, time_getter: Reference<TG>, time_delta: Time, ) -> Self

Constructor with a custom time delta.

pub fn set_delta(&mut self, time_delta: Time)

Set the time delta.

pub fn set_time(&mut self, time: Time) -> NothingOrError<E>

Define now as a given time in the history. Mostly used when construction and use are far apart in time.

Trait Implementations

impl<G, TG: TimeGetter<E>, E: Copy + Debug> Getter<G, E> for GetterFromHistory<'_, G, TG, E>

fn get(&self) -> Output<G, E>

Get something.

impl<G, TG: TimeGetter<E>, E: Copy + Debug> Updatable<E> for GetterFromHistory<'_, G, TG, E>

fn update(&mut self) -> NothingOrError<E>

As this trait is very generic, exactly what this does will be very dependent on the implementor.
