Struct parol::analysis::lookahead_dfa::DFAState

pub struct DFAState {
    pub id: StateIndex,
    pub accepted: bool,
    pub prod_num: ProductionIndex,
}

Data structure to represent a DFA state

Fields

id: StateIndex

A unique state number, actually the index into the array of states.

accepted: bool

The state is either accepting or not.

prod_num: ProductionIndex

Used to detect conflicts. A conflict can occur in union operations. When combining two states that are both accepted and have different production numbers a conflict is detected.

Trait Implementations

impl Clone for DFAState

fn clone(&self) -> DFAState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DFAState

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

Formats the value using the given formatter.

impl Default for DFAState

fn default() -> DFAState

Returns the “default value” for a type.

impl Display for DFAState

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

Formats the value using the given formatter.
