impl Visitor for GameExtractor

type Result = ()

Value produced by the visitor after reading a game.

fn begin_game(&mut self)

Called at the start of the game.

fn header(&mut self, _key: &[u8], _value: RawHeader<'_>)

Called when parsing a game header like [White "Deep Blue"].

fn san(&mut self, san_plus: SanPlus)

Called for each move, like Nf3+.

fn begin_variation(&mut self) -> Skip

Called for each (. May skip over the following variation directly to end_variation() (or to end_game() if no matching ) follows before the end of the game.

fn end_game(&mut self) -> Self::Result

Called after parsing a game. Can produce a custom result.

fn begin_headers(&mut self)

Called directly before reading game headers.

fn end_headers(&mut self) -> Skip

Called after reading the headers of a game. May skip quickly over the following move text directly to end_game().

fn nag(&mut self, _nag: Nag)

Called for each numeric annotation glyph like !? or $7.

fn comment(&mut self, _comment: RawComment<'_>)

Called for each { comment }.

fn end_variation(&mut self)

Called for each ). It is not guaranteed that there was a matching (.

fn outcome(&mut self, _outcome: Option<Outcome>)

Called for each game termination, like * or 1-0.
