Struct FirstSet

pub struct FirstSet {
    pub symbols: BitSet,
    pub has_epsilon: bool,
}

The first set of a nonterminal.

Fields

symbols: BitSet

The first symbols.

has_epsilon: bool

Whether one of the productions is empty.

Trait Implementations

impl Clone for FirstSet

fn clone(&self) -> FirstSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FirstSet

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

Formats the value using the given formatter.

impl Hash for FirstSet

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FirstSet

fn eq(&self, other: &FirstSet) -> 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.
