Struct lrpar::CTParser

pub struct CTParser<StorageT = u32>
where
    StorageT: Eq + Hash,
{ /* private fields */ }

An interface to the result of CTParserBuilder::build().

Implementations

impl<StorageT> CTParser<StorageT>

where StorageT: 'static + Debug + Hash + PrimInt + Unsigned, usize: AsPrimitive<StorageT>,

pub fn regenerated(&self) -> bool

Returns true if this compile-time parser was regenerated or false if it was not.

pub fn token_map(&self) -> &HashMap<String, StorageT>

Returns a HashMap from lexeme string types to numeric types (e.g. INT: 2), suitable for handing to a lexer to coordinate the IDs of lexer and parser.

pub fn conflicts( &self, _: UnstableApi ) -> Option<(&YaccGrammar<StorageT>, &StateGraph<StorageT>, &StateTable<StorageT>, &Conflicts<StorageT>)>

If there are any conflicts in the grammar, return a tuple which allows users to inspect and pretty print them; otherwise returns None. If the grammar was not regenerated, this will always return None, even if the grammar actually has conflicts.

Note: The conflicts feature is currently unstable and may change in the future.
