Trait SpringTarget 

pub trait SpringTarget: 'static {
    type Output;

    // Required methods
    fn target(&self) -> f32;
    fn resolve(&self, value: f32) -> Self::Output;
}

A value that a one-dimensional spring can target.

The spring solver works on one f32 coordinate. A target maps its value into that coordinate and maps the sampled coordinate back into the output consumed by the animator. Built-in targets are f32, Pixels, Rems, AnimationPhase and bool (which maps to 0.0 or 1.0).

Examples

use gpui::{SpringTarget, px};

assert_eq!(px(12.).target(), 12.0);
assert_eq!(px(12.).resolve(14.0), px(14.));
assert_eq!(true.target(), 1.0);

Required Associated Types

type Output

The value that the spring animator receives.

Required Methods

fn target(&self) -> f32

Returns this target as a coordinate for the spring.

fn resolve(&self, value: f32) -> Self::Output

Converts a spring coordinate into the output the animator receives.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
