Struct Constant

ast/ast.go:257–280

Constant represents a constant symbol and other structures (e.g. pair, list map, struct).

// Constant represents a constant symbol and other structures (e.g. pair, list map, struct).
type Constant struct {
	// The (runtime) type of this constant.
	Type ConstantType

	// If Type \in {StringType, BytesType}, the data itself.
	// Otherwise, a string representation.
	Symbol string

	// For NumberType, the number value (int64 or the bytes of a float64).
	// For other types it contains a hash code of the value.
	NumValue int64

	// For a pair constant, the first component.
	// For a list constant, the head of the list.
	// For a map constant, the first map entry.
	// For a struct constant, the first field.
	fst *Constant

	// For a pair constant, the second component
	// For a list constant, the tail of the list.
	// For a map constant, the tail of the entries.
	// For a struct constant, the tail of the fields.
	snd *Constant
}

// Name constructs a new name constant while checking that constant symbol starts with a '/' and
// does not contain empty parts.
