cbor/encoding.h exposes a low-level encoding API to encode CBOR objects on the fly. Unlike cbor_serialize, these functions take logical values (integers, floats, strings, etc.) instead of cbor_item_t. The client is responsible for constructing the compound types correctly (e.g. terminating arrays).
Streaming encoding is typically used to create an streaming (indefinite length) CBOR strings <type_2_byte_strings>, byte strings <type_3_strings>, arrays <type_4_arrays>, and maps <type_5_maps>. Complete example: examples/streaming_array.c
