pub fn cbor_det_parse<'a>(input: &'a [u8]) -> Option<(CborDet<'a>, &'a [u8])>Expand description
Tries to parse a Deterministic CBOR object from the first bytes of
input, following RFC 8949 Section 4.2.1, minus floating-point
values. Returns None in case of failure, or Some(object, rem)
in case of success, where rem is the remainder of the input
slice past those first bytes of input that contain the valid
binary representation of
input. This function does not perform a deep parse of input,
it only copies the object type, tag and/or size of the top-most
object. As such, it uses constant stack space (including data
validation.) “Destructor” functions are to be used on the returned
object, to examine each level of nesting one at a time. NOTE: This
implementation checks for the basic validity constraints of
Section 5.3.1, i.e. the absence of duplicate map keys (which is a
consequence of the deterministic encoding.), and the
well-formedness of UTF-8 text strings.
