Trait Newton1d 

pub trait Newton1d:
    Iterate
    + Copy
    + Debug {
    // Required methods
    fn could_be_zero(self) -> bool;
    fn step(value: Self, slope: Self) -> GeopResult<(Self, f64)>;
    fn settle(self, step: Self, lo: Self, hi: Self) -> Self;
}

A number newton_1d runs in: plain f64, or a scalar.

Required Methods

fn could_be_zero(self) -> bool

Whether self, a function’s value, could be zero.

fn step(value: Self, slope: Self) -> GeopResult<(Self, f64)>

The Newton step value / slope and its size, or why there is none.

fn settle(self, step: Self, lo: Self, hi: Self) -> Self

self - step, as the seed of the next step: clamped into (lo, hi), and sharp — it is a free choice.

Dyn Compatibility

This trait is not dyn compatible.

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

Implementations on Foreign Types

impl Newton1d for f64

fn could_be_zero(self) -> bool

fn step(value: Self, slope: Self) -> GeopResult<(Self, f64)>

fn settle(self, step: Self, lo: Self, hi: Self) -> Self

Implementors

impl Newton1d for Scalar

Sharpened before clamping: clamped’s comparisons are exact on a sharp value, so the seed stays in the domain.
