Struct shakmaty_syzygy::Tablebases

pub struct Tablebases<S: Position + Clone + Syzygy> { /* fields omitted */ }

A collection of tables.

Methods

impl<S: Position + Clone + Syzygy> Tablebases<S>

pub fn new() -> Tablebases<S>

Create an empty collection of tables.

pub fn add_directory<P: AsRef<Path>>(&mut self, path: P) -> Result<()>

Scan a directory for relevant tables.

Tables are selected by filename, e.g. KQvKP.rtbz. The files are not actually opened. This happens lazily when probing.

Errors

Returns an error result when:

• The path does not exist.
• path is not a directory.
• The process lacks permissions to list the directory.

pub fn probe_wdl(&self, pos: &S) -> Result<Wdl, SyzygyError>

Probe tables for the Wdl value of a position.

Errors

See SyzygyError for possible error conditions.

Panics

Corrupted tables may or may not cause panics, especially due to integer overflow in debug mode. Ideally a future version will not panic in such cases.

pub fn probe_dtz(&self, pos: &S) -> Result<Dtz, SyzygyError>

Probe tables for the Dtz value of a position.

Errors

See SyzygyError for possible error conditions.

Panics

Corrupted tables may or may not cause panics, especially due to integer overflow in debug mode. Ideally a future version will not panic in such cases.

Trait Implementations

impl<S: Debug + Position + Clone + Syzygy> Debug for Tablebases<S>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<S: Position + Clone + Syzygy> Default for Tablebases<S>

fn default() -> Tablebases<S>

Returns the "default value" for a type.
