/**
 * Represents a primitive literal.
 * This is similar to the primitives supported in the well-known type
 * `google.protobuf.Value`, but richer so it can represent CEL's full range of
 * primitives.
 * Lists and structs are not included as constants as these aggregate types may
 * contain [Expr][google.api.expr.v1beta1.Expr] elements which require evaluation and are thus not constant.
 * Examples of literals include: `"hello"`, `b'bytes'`, `1u`, `4.2`, `-2`,
 * `true`, `null`.
