Error when trying to create a Position from an illegal Setup.

See PositionErrorKinds for possible reasons.

Implementations

impl<P> PositionError<P>

pub fn ignore_invalid_castling_rights(self) -> Result<P, Self>

Discards invalid castling rights to recover from PositionErrorKinds::INVALID_CASTLING_RIGHTS.

pub fn ignore_invalid_ep_square(self) -> Result<P, Self>

Discards invalid en passant squares to recover from PositionErrorKinds::INVALID_EP_SQUARE.

pub fn ignore_too_much_material(self) -> Result<P, Self>

Get the position despite PositionErrorKinds::TOO_MUCH_MATERIAL.

Note that other programs may not work with too much material.

pub fn ignore_impossible_check(self) -> Result<P, Self>

Get the position despite PositionErrorKinds::IMPOSSIBLE_CHECK (not be be confused with PositionErrorKinds::OPPOSITE_CHECK).

Note that other programs may not work in such a situation.

pub fn kinds(&self) -> PositionErrorKinds

Returns the reasons for this error.

fn clone(&self) -> PositionError<P>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<P> Debug for PositionError<P>

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

Formats the value using the given formatter.

impl<P> Display for PositionError<P>

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

impl<P> Error for PositionError<P>

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting
