Detailed Description

Descriptor for a mixed-type JSON array.

This structure describes a top-level JSON array whose elements may be of different types (primitives, objects, arrays, or nested mixed arrays). Each element in the array is described by an entry in a descriptor array.

Mixed arrays are useful for parsing and encoding JSON arrays that do not have a homogeneous element type, such as:

[ "string", 42, { "foo": 1 }, [1,2,3], true ]

Note

This structure and its associated macros are intended for use with the mixed array parsing and encoding APIs (see json_mixed_arr_parse()).
