Trait EvalDyn 

pub(super) trait EvalDyn {
    // Required method
    fn eval_into(&self, alpha: f64, output: &mut Vec<DynItem>);

    // Provided method
    fn sim_step(&self) -> Option<f64> { ... }
}

The erased visual-leaf protocol: Eval without its type.

This is the only type-erased box in the runtime tree (NodeContent::Leaf) — the open world of user evaluators. Containers are closed runtime variants and never implement this.

Required Methods

fn eval_into(&self, alpha: f64, output: &mut Vec<DynItem>)

Evaluate this leaf’s content at its normalized progress alpha, pushing the resulting erased items into output.

Provided Methods

fn sim_step(&self) -> Option<f64>

The iterative content step, if this leaf is an iterative segment.

Dyn Compatibility

This trait is dyn compatible.

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