What a TacticsOrder asks the game, once per order call. The game’s hooks hold the state’s Threats and GoalDistance, built in prepare.

Required Associated Types

type Piece: Eq + Copy

The game’s id of a piece.

Required Methods

fn prepare(&mut self, rules: &R)

Called first: build this state’s Threats and GoalDistance.

fn classify(&mut self, rules: &R, command: &R::Command) -> Kind<Self::Piece>

What command is, called once per legal command, in the legal order.

fn pick(&mut self, rules: &R) -> Option<R::Command>

The game’s own pick (an AI’s command), if it has one; it may also be a strike or a step, and is listed once.

fn at(&self, rules: &R, piece: Self::Piece) -> Option<Pos>

Where piece stands now.

fn distance(&mut self, rules: &R, piece: Self::Piece, from: Pos) -> Option<u32>

How far piece would walk from from to the nearest goal; None with no walk.

fn safe(&self, rules: &R, at: Pos) -> bool

Whether no threat reaches at.

Dyn Compatibility

This trait is dyn compatible.

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