Trait ToF32 

pub trait ToF32 {
    // Required method
    fn to_f32(&self) -> Option<f32>;
}

Trait for converting data types to f32 for curve editing.

Implement this trait on your data enum to enable egui-keyframe integration with GenericValue. Return None for types that cannot be displayed as scalar curves (e.g., strings, colors, transforms).

Example

impl ToF32 for MyData {
    fn to_f32(&self) -> Option<f32> {
        match self {
            MyData::Float(f) => Some(*f),
            MyData::Vec3(_) => None, // Can't display as single curve.
        }
    }
}

Required Methods

fn to_f32(&self) -> Option<f32>

Convert the data value to f32 for curve display.

Returns None for non-numeric types.
