Struct glissade::InertialValue

pub struct InertialValue<T: TransitionItem> { /* private fields */ }

A value that smoothly goes to the target during a specific time. The target can be changed at any time. No jumps will occur. It’s expected that time is always increasing. Every method receives current_time as a parameter to allow testing, and have a consistent behavior during a single animation frame.

Implementations

impl<T: TransitionItem> InertialValue<T>

pub fn new(value: T, start_time: SystemTime) -> Self

Create a new inertial value at a specific time.

pub fn is_finished(&self, current_time: SystemTime) -> bool

Check if the inertial value reached the target.

pub fn target(&self) -> T

Get the target value.

pub fn end_time(&self) -> SystemTime

Get transition end time.

pub fn get(&self, current_time: SystemTime) -> T

Get the value of the inertial value at a specific time.

• current_time - The time to get the value of the inertial value, usually SystemTime::now().

pub fn go_to( self, target: T, current_time: SystemTime, duration: Duration, ) -> Self

Create child inertial value with a new target at a specific time. Easing is set to default (QuadraticInOut).

• target - The new target value.
• current_time - The time to start the transition, usually SystemTime::now().
• duration - The duration of the transition.

pub fn ease_to( self, target: T, current_time: SystemTime, duration: Duration, easing: Easing, ) -> Self

Create child inertial value with a new target, easing and start time.

• target - The new target value.
• start_time - The time to start the transition, usually SystemTime::now().
• duration - The duration of the transition.

Trait Implementations
