An implementation of the JSONPath A spec in Rust, with several extensions added on.

Extensions

  • Parent selector ^, used as $.a.b.^ or $['a']['b'][^]. Matches the parent of the currently selected object.
  • Subpath selectors, used as $['a'][$.b.id] or $['a'][@.sum.id]. Evaluates the subpath, then selects items with keys same as the result of the subpath.
  • ID selector ~, used at the end of the path as @.a.b~ or $['a']['b']~. Can be used in filters to compare against the ID of a matched item. Doesn't yet work at the top level.
