Struct State 

pub struct State<Term, NonTerm> {
    pub shift_goto_map_term: BTreeMap<Term, usize>,
    pub shift_goto_map_nonterm: BTreeMap<NonTerm, usize>,
    pub reduce_map: BTreeMap<Term, BTreeSet<usize>>,
    pub ruleset: BTreeSet<ShiftedRuleRef>,
}

state for internal usage during grammar building stage

Fields

shift_goto_map_term: BTreeMap<Term, usize>

shift_goto_map_nonterm: BTreeMap<NonTerm, usize>

reduce_map: BTreeMap<Term, BTreeSet<usize>>

ruleset: BTreeSet<ShiftedRuleRef>

Implementations

impl<Term, NonTerm> State<Term, NonTerm>

pub fn new() -> State<Term, NonTerm>

pub fn unshifted_ruleset(&self) -> impl Iterator<Item = ShiftedRuleRef>

shift -= 1 for all rules in the ruleset

Trait Implementations

impl<Term, NonTerm> Clone for State<Term, NonTerm>

where Term: Clone, NonTerm: Clone,

fn clone(&self) -> State<Term, NonTerm>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<Term, NonTerm> Debug for State<Term, NonTerm>

where Term: Debug, NonTerm: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<Term, NonTerm> Default for State<Term, NonTerm>

fn default() -> State<Term, NonTerm>

Returns the “default value” for a type.

impl<Term, NonTerm> From<State<Term, NonTerm>> for IntermediateState<Term, NonTerm, usize, usize>

where Term: Ord,

fn from( state: State<Term, NonTerm>, ) -> IntermediateState<Term, NonTerm, usize, usize>

Converts to this type from the input type.
