Expand description
Value
represents a dynamically typed value which can be either
null, a number, a string, a boolean, a recursive struct value, or a
list of values. A producer of value is expected to set one of these
variants. Absence of any variant indicates an error.
The JSON representation for Value
is JSON value.
