Struct Dfa 

pub struct Dfa { /* private fields */ }

Implementations

impl Dfa

pub const fn new(atn_start_state: usize, decision: usize) -> Self

pub const fn with_max_token_type( atn_start_state: usize, decision: usize, max_token_type: i32, ) -> Self

pub const fn decision(&self) -> usize

pub const fn atn_start_state(&self) -> usize

pub const fn max_token_type(&self) -> i32

pub fn states(&self) -> &[DfaState]

pub const fn start_state(&self) -> Option<usize>

pub const fn set_start_state(&mut self, state_number: usize)

pub const fn is_dirty(&self) -> bool

Whether this DFA learned any new state/edge/start since it was created or last cleared. The shared-cache merge uses this to skip untouched DFAs.

pub const fn clear_dirty(&mut self)

Clears the dirty flag, marking the current contents as the clean baseline (called after publishing to / cloning from the shared cache).

pub const fn is_precedence_dfa(&self) -> bool

pub fn set_precedence_dfa(&mut self, precedence_dfa: bool)

pub fn precedence_start_state(&self, precedence: usize) -> Option<usize>

pub fn set_precedence_start_state( &mut self, precedence: usize, state_number: usize, )

pub fn add_state(&mut self, state: DfaState) -> usize

Inserts a DFA state or returns the existing state number for an equivalent ATN configuration set.

pub fn state(&self, state_number: usize) -> Option<&DfaState>

pub fn state_mut(&mut self, state_number: usize) -> Option<&mut DfaState>

Trait Implementations

impl Clone for Dfa

fn clone(&self) -> Dfa

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Dfa

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

Formats the value using the given formatter.

impl Eq for Dfa

impl PartialEq for Dfa

fn eq(&self, other: &Dfa) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
