Implementations

impl<Term> LookaheadRuleRefSet<Term>

pub fn new() -> LookaheadRuleRefSet<Term>

pub fn add(&mut self, rule: ShiftedRuleRef, lookaheads: BTreeSet<Term>) -> bool

where Term: Ord,

Trait Implementations

impl<Term> Clone for LookaheadRuleRefSet<Term>

where Term: Clone,

fn clone(&self) -> LookaheadRuleRefSet<Term>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Term> Debug for LookaheadRuleRefSet<Term>

where Term: Debug,

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

Formats the value using the given formatter.

impl<Term> Default for LookaheadRuleRefSet<Term>

where Term: Default,

fn default() -> LookaheadRuleRefSet<Term>

Returns the “default value” for a type.

impl<Term> Ord for LookaheadRuleRefSet<Term>

where Term: Ord,

fn cmp(&self, other: &LookaheadRuleRefSet<Term>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<Term> PartialEq for LookaheadRuleRefSet<Term>

where Term: PartialEq,

fn eq(&self, other: &LookaheadRuleRefSet<Term>) -> 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.

impl<Term> PartialOrd for LookaheadRuleRefSet<Term>

where Term: PartialOrd,

fn partial_cmp(&self, other: &LookaheadRuleRefSet<Term>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
