Struct backgammon::rules::Cube

pub struct Cube { /* private fields */ }

Represents a Backgammon cube (doubling cube).

This cube represents an increase in the value of the current game. The cube – a doubling of the value of the game – can be offered by any player the first time it is used. After that, it can only be offered by the player who last took the cube.

Implementations

impl Cube

pub fn value(&self) -> u64

Returns the value of the cube

pub fn owner(&self) -> Player

Returns the owner of the cube

pub fn set(&mut self, value: u64) -> Result<(), Error>

Set the value of the cube.

Internally, we store the value of the cube as an exponent of 2 as u8. Therefore there is a technical limit of 2^64 on the value of the cube, which we believe is a reasonable limit.

pub fn set_owner(&mut self, owner: Player)

Set owner of cube.

pub fn offer(&self, opponent: Player) -> Result<u64, Error>

Calculate the next value of the cube to offer it to the opponent

Trait Implementations

impl Clone for Cube

fn clone(&self) -> Cube

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Cube

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

Formats the value using the given formatter.

impl Default for Cube

fn default() -> Cube

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Cube

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<Cube> for Cube

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Cube

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
