/**
 *  * Represents a primitive literal.
 *
 * Named 'Constant' here for backwards compatibility.
 *
 * This is similar as 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.v1alpha1.Expr] elements which require
 * evaluation and are thus not constant.
 *
 * Examples of literals include: `"hello"`, `b'bytes'`, `1u`, `4.2`, `-2`,
 * `true`, `null`.
 * 
 *
 * Protobuf type {@code google.api.expr.v1alpha1.Constant}
