Enum Quantifier 

pub enum Quantifier {
    ZeroOrOne,
    ZeroOrMore,
    OneOrMore,
    Exactly(usize),
    Range(usize, usize),
}

A quantifier applied to a single term in a parent’s content expression.

Mirrors the ProseMirror content-expression grammar used by @atlaskit/adf-schema. Range is used for the only known range case (layoutSection permits 2–3 layoutColumn children); Exactly is used for mediaSingle’s required media child.

Variants

ZeroOrOne

? — zero or one (optional).

ZeroOrMore

* — zero or more.

OneOrMore

+ — one or more.

Exactly(usize)

{n} — exactly n.

Range(usize, usize)

{min,max} — between min and max inclusive.

Implementations

impl Quantifier

pub fn satisfied_by(&self, n: usize) -> bool

True when a count of n is acceptable for this quantifier.

Trait Implementations

impl Clone for Quantifier

fn clone(&self) -> Quantifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Quantifier

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

Formats the value using the given formatter.

impl PartialEq for Quantifier

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