Struct IterativeFn 

pub struct IterativeFn<S, F> {
    eval: F,
    output: PhantomData<fn() -> S>,
}

An IterativeEval backed by a stepping function.

The wrapper binds the function’s mutable input type as the evaluator’s unique Output. Prefer Iterative::from_fn to constructing this type directly.

Fields

eval: F

output: PhantomData<fn() -> S>

Implementations

impl<S, F> IterativeFn<S, F>

where F: Fn(&mut S, f64, f64),

pub fn new(eval: F) -> Self

Bind a stepping function to its state type.

Trait Implementations

impl<S, F> IterativeEval for IterativeFn<S, F>

where F: Fn(&mut S, f64, f64),

type Output = S

State produced and advanced by this evaluator.

fn step(&self, output: &mut Self::Output, alpha: f64, delta_alpha: f64)

Advance the state by one progress step.
