Consumes games from a reader.

Associated Types

type Result

Required Methods

fn end_game(&mut self, game: &'pgn [u8]) -> Self::Result

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

Provided Methods

fn begin_game(&mut self)

Called at the start of a game.

fn begin_headers(&mut self)

Called directly before reading game headers.

fn header(&mut self, _key: &'pgn [u8], _value: &'pgn [u8])

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

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 san(&mut self, _san: San)

Called for each move, like Nf3.

fn nag(&mut self, _nag: Nag)

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

fn comment(&mut self, _comment: &'pgn [u8])

Called for each { comment } with the whole comment as a byte slice, excluding the braces.

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 ) follows before the end of the game).

fn end_variation(&mut self)

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

fn outcome(&mut self, _outcome: Outcome)

Called for each game termination, like 1-0.
