Struct CompositeStrategy 

pub struct CompositeStrategy<S1: Strategy, S2: Strategy> { /* private fields */ }

A Strategy which uses two strategies by first applying one and then the other on the output of the first one. If any child changed the state, this strategy is defined to have changed the state aswell.

Implementations

impl<S1: Strategy, S2: Strategy> CompositeStrategy<S1, S2>

pub fn new(s1: S1, s2: S2) -> CompositeStrategy<S1, S2>

Creates a new composite strategy from the two children strategies.

Arguments

• s1: The strategy which is applied first.
• s2: The strategy which is applied second.

Trait Implementations

impl<S1: Strategy + Clone, S2: Strategy + Clone> Clone for CompositeStrategy<S1, S2>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S1: Strategy, S2: Strategy> Strategy for CompositeStrategy<S1, S2>

fn apply(&self, sudoku_info: &mut SudokuInfo<impl Constraint + Clone>) -> bool

Applies this strategy to the given Sudoku. The strategy may rely on and modify the information in the given sudoku_info. This instance is given to other strategies that participate in the solution and/or future iterations of the same strategy. It can thus be used to communicate insights.
