           bound: BoundType,
           depth: Depth,
           move_digest: MoveDigest)
           -> Self;

}

A trait for transposition table entries.

Required Methods

Creates a new instance.

  • value -- The value assigned to the position. Must not be VALUE_UNKNOWN.

  • bound -- The accuracy of the assigned value.

  • depth -- The depth of search. Must be between DEPTH_MIN and DEPTH_MAX.

  • move_digest -- Best or refutation move digest, or MoveDigest::invalid() if no move is available.

Creates a new instance.

The only difference between this function and new is that this function requires one additional parameter:

  • static_eval -- Position's static evaluation, or VALUE_UNKNOWN.

Important note: static_eval will be ignored if there is no field allotted for it in the underlying memory structure.

Returns the value assigned to the position.

Returns the accuracy of the assigned value.

Returns the search depth for the assigned value.

Returns best or refutation move digest, or MoveDigest::invalid() if no move is available.

Returns position's static evaluation, or VALUE_UNKNOWN.
