Expand description

A RON value that can represent any valid RON data.

This enum distinguishes between all RON syntactic forms:

  • Seq: sequences [a, b, c]
  • Tuple: tuples (a, b, c)
  • Map: maps with arbitrary keys { key: value }
  • Struct: anonymous structs with named fields (x: 1, y: 2)
  • Named: named types (structs/enums) like Point(x: 1) or Option::Some(1)

Seq(Vec<Value>)

Sequence: [a, b, c]

§

Tuple(Vec<Value>)

Tuple: (a, b, c) - positional elements

§

Map(Map)

Map: { key: value } - arbitrary Value keys

§

Struct(StructFields)

Anonymous struct: (x: 1, y: 2) - named fields, no type name

§

Named

Named type: Point, Point(1, 2), Point(x: 1), or Type::Variant(...)

The name field stores the full path as-is (e.g., "Type::Variant").

Fields

§name: String

The type/variant name, e.g., "Point" or "Option::Some"

§content: NamedContent
