Every cbor_item_t has a cbor_type associated with it - these constants correspond to the types specified by the CBOR standard:
cbor_type
To find out the type of an item, one can use
cbor_typeof
Please note the distinction between functions like cbor_isa_uint() and cbor_is_int(). The following functions work solely with the major type value.
Alternatively, there are functions to query each particular type.
Warning
Passing an invalid cbor_item_t reference to any of these functions results in undefined behavior.
cbor_isa_uint
cbor_isa_negint
cbor_isa_bytestring
cbor_isa_string
cbor_isa_array
cbor_isa_map
cbor_isa_tag
cbor_isa_float_ctrl
These functions provide information about the item type from a more high-level perspective
cbor_is_int
cbor_is_float
cbor_is_bool
cbor_is_null
cbor_is_undef
