only.Expand description
Convert a CoAP code to dotted notation
This expresses the class number of a code, followed by a dot and the two-digit detail, into a String. That format is the common human-readable expression of CoAP codes, as it eases the comparison to the (dot-less) codes of HTTP.
Example:
let g: String = to_dotted(GET);
assert_eq!(g, "0.01");
let d = to_dotted(PRECONDITION_FAILED);
assert_eq!(d, "4.12");
This is equivalent in functionality to format_dotted
, which may be
used as a replacement in no_std
settings.
