Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Union(Vec<UnionComponent>)

A union of multiple selectors, [1, 3, 9]

StepRange(StepRange)

A range selector with explicit step, [1:5:2]

Range(Range)

A range selector with implicit step, [2:8]

Wildcard(Star)

A wildcard selector to get all children, [*]

Parent(Caret)

A parent selector to retrieve the parent of the matched item, [^]

Path(SubPath)

A sub-path selector to retrieve keys from a matched path, [$.foo.bar]

Filter(Filter)

A filter selector to retrieve items matching a predicate, [?(expr)]

Literal(BracketLit)

A literal selector to retrieve the mentioned keys, [6] or ['qux']
