Implementations§

source§

impl AmbiguousWdl

source

pub fn signum(self) -> i32

source

pub fn from_dtz_and_halfmoves( dtz: MaybeRounded<Dtz>, halfmoves: u32 ) -> AmbiguousWdl

Gets the WDL value for a position with the given dtz and halfmoves counter.

The value will always be unambiguous if halfmoves == 0.

source

pub fn after_zeroing(self) -> Wdl

Get the unambiguous Wdl, assuming that the value has been reached directly after a capture or pawn move, or by following the tablebase mainline from a capture or pawn move.

source

pub fn is_ambiguous(self) -> bool

Returns true if self does not uniquely correspond to a Wdl.

source

pub fn is_unambiguous(self) -> bool

Returns true if self uniquely corresponds to a Wdl.

source

pub fn unambiguous(self) -> Option<Wdl>

Returns the uniquely corresponding Wdl, or None if ambiguous.
