Struct vek::transition::Transition

pub struct Transition<T, F, Progress = f32> {
    pub start: T,
    pub end: T,
    pub progress: Progress,
    pub progress_mapper: F,
}

A convenience structure for storing a progression from one value to another.

Fields

start: T

The value when progress gets close to 0.

end: T

The value when progress gets close to 1.

progress: Progress

Expected to be between 0 and 1.

progress_mapper: F

Functor that maps the current progress value to a LERP factor.

Methods

impl<T, F, Progress> Transition<T, F, Progress>

fn with_mapper(start: T, end: T, progress_mapper: F) -> Self where
    Progress: Zero, 

Creates a new Transition from start and end values and progress_mapper, setting progress to zero.

fn with_mapper_and_progress(
    start: T,
    end: T,
    progress_mapper: F,
    progress: Progress
) -> Self

Creates a new Transition from start, end, progress_mapper and progress values.

fn into_range(self) -> Range<T>

Converts this into a Range, dropping the progress and progress_mapper values.

impl<T, F, Progress> Transition<T, F, Progress> where
    F: ProgressMapper<Progress>, 

fn into_current(self) -> T where
    T: Lerp<Progress, Output = T>,
    Progress: Clamp + Zero + One, 

Gets the transition's current state, clamping progress to [0;1].

fn into_current_unclamped(self) -> T where
    T: Lerp<Progress, Output = T>, 

Gets the transition's current state using the progress value as-is.

fn into_current_precise(self) -> T where
    T: Lerp<Progress, Output = T>,
    Progress: Clamp + Zero + One, 

Gets the transition's current state, clamping progress to [0;1].

fn into_current_unclamped_precise(self) -> T where
    T: Lerp<Progress, Output = T>, 

Gets the transition's current state using the progress value as-is.

fn current<'a>(&'a self) -> T where
    &'a T: Lerp<Progress, Output = T>,
    Progress: Copy + Clamp + Zero + One, 

Gets the transition's current state, clamping progress to [0;1].

fn current_unclamped<'a>(&'a self) -> T where
    &'a T: Lerp<Progress, Output = T>,
    Progress: Copy, 

Gets the transition's current state using the progress value as-is.

fn current_precise<'a>(&'a self) -> T where
    &'a T: Lerp<Progress, Output = T>,
    Progress: Copy + Clamp + Zero + One, 

Gets the transition's current state, clamping progress to [0;1].

fn current_unclamped_precise<'a>(&'a self) -> T where
    &'a T: Lerp<Progress, Output = T>,
    Progress: Copy, 

Gets the transition's current state using the progress value as-is.
