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.

Implementations

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

pub 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.

pub 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.

pub fn into_range(self) -> Range<T>

pub 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.

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

impl<T, Progress> Transition<T, IdentityProgressMapper, Progress>

pub fn new(start: T, end: T) -> Self where
    Progress: Zero, 

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

pub fn with_progress(start: T, end: T, progress: Progress) -> Self

Creates a new LinearTransition from start, end and progress values.
