Implementations

impl Variant

pub fn team_default() -> Self

The default variant for the team gamemode.

pub fn ffa_default() -> Self

The default for the ffa and solo gamemodes

pub fn fairy(&self) -> bool

Returns true if there are any non-standard pieces in play (or could promote to such a piece)

pub fn pawn_base_rank(&self) -> usize

Distance of the pans base rank from the edge of the board.

Trait Implementations

impl Clone for Variant

fn clone(&self) -> Variant

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Variant

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

Formats the value using the given formatter.

impl Display for Variant

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

Formats the value using the given formatter.

impl Hash for Variant

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Variant

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

Tests for self and other values to be equal, and is used by ==.

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

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