Struct Sampling 

pub struct Sampling { /* private fields */ }

A shaded heatmap sampled one cell at a time, row by row from the top, for a problem whose every evaluation is expensive.

The caller spreads the cells over frames and shows Self::partial meanwhile. The finished result is the one shaded returns, bit for bit.

Implementations

impl Sampling

pub fn new(problem: &Problem, size: usize) -> Option<Self>

A size × size sampling of problem with no cell done; None for a problem without exactly two parameters.

pub const fn problem(&self) -> &Problem

The problem being sampled.

pub fn done(&self) -> usize

How many cells are done.

pub const fn total(&self) -> usize

How many cells there are.

pub fn step(&mut self) -> bool

Samples the next cell. Returns whether one was left to sample.

pub fn partial(&self) -> Field

The shaded cells so far, every cell not yet sampled NaN.

pub fn finish(self) -> Option<Shaded>

The finished heatmap, or None while cells remain.

Trait Implementations

impl Clone for Sampling

fn clone(&self) -> Sampling

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Sampling

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Sampling

fn eq(&self, other: &Sampling) -> bool

Equality operator ==.
