Function spring 

pub fn spring(frame: u32, fps: f64, config: SpringConfig) -> f64

Compute the spring value at frame (0-indexed).

Arguments

• frame — current frame number
• fps — frames per second of the composition
• config — spring physics configuration

Returns a value interpolated between 0.0 (start) and 1.0 (settled). Use crate::interpolate::interpolate to map this to any output range.

Notes

Uses the same spring model as Remotion’s springCalculation() from spring-utils.ts. Valid inputs retain the original integer-frame behavior.

Panics

Panics for invalid parameters or a requested frame beyond 100,000. Use spring_with_options to handle errors explicitly.
