Holds all the rule settings

Fields

points: u32

The amount of points to reach for declaring a winner of the match, default is 7.

beaver: bool

When offered the cube, allow to re-double but keep it, default is false.

raccoon: bool

If a player plays “beaver”, the other may double again, letting the opponent keep the cube. Default is false

murphy: bool

If both players roll the same opening number, the dice is doubled, remaining in the middle of the board. Default is false.

murphy_limit: u8

How often to apply automatic doubling rule. 0 means always on. Default is 0.

jacoby: bool

Gammon and Backgammon only count for double or triple values if the cube has already been offered. Default is false.

crawford: bool

When a player first reaches a score of points - 1, no doubling is allowed for the following game. Default is true.

holland: bool

Permits to double after Crawford game only if both players have rolled at least twice. Default is false.

impl MatchRules for Rules

Implements SetRules for Rules

fn with_points(self, points: u32) -> Self

Set the amount of points to reach for declaring a winner

fn with_crawford(self) -> Self

When a player first reaches a score of points - 1, no doubling is allowed for the following game

impl Ord for Rules

fn cmp(&self, other: &Rules) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Rules> for Rules

fn eq(&self, other: &Rules) -> 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 PartialOrd<Rules> for Rules

fn partial_cmp(&self, other: &Rules) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Rules

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

Serialize this value into the given Serde serializer.

impl Copy for Rules
