Expand description

A raw value in a memory slot — pre-binding analogue of crate::Value.

Differs from Value in two ways:

  • RawSymbol carries a RawSymbolName rather than a resolved SymbolId.
  • Extra variants that only exist in surface syntax: TypedSymbol (the @name:Kind annotation), Bareword (predicate or string literal depending on slot), List (parenthesized lists like participants / derived_from), and Nil.

Variants§

§

RawSymbol(RawSymbolName)

@name.

§

TypedSymbol

@name:Kind.

Fields

§name: RawSymbolName

Symbol name without the @.

§kind: String

Kind annotation without the leading :.

§

Bareword(String)

A bareword. In predicate slots resolves to a Predicate-kind symbol; elsewhere resolves to a string literal (Value::String).

§

String(String)

A quoted UTF-8 string literal.

§

Integer(i64)

A signed integer.

§

Float(f64)

An IEEE 754 binary64 float.

§

Boolean(bool)

A boolean.

§

Nil

nil — represents Option::None in nullable positions.

§

List(Vec<RawValue>)

A parenthesized (...) list — used for participants, derived_from, and similar multi-value slots. Each element is itself a RawValue.

§

Timestamp(ClockTime)

A timestamp token — stored as milliseconds. Pre-validated by the lexer to look like an ISO-8601 timestamp.

§

TimestampRaw(String)

A raw timestamp text that the lexer could not yet convert to a ClockTime (e.g. because the parser is collecting the value for a slot where the binder does the conversion). Escape hatch used by the bind stage; the parser itself always produces Timestamp(ClockTime) where possible.
