This utility struct provides a namespace for a suite of functions operating on objects of type 'FuzzDataView'and providing the consumption of fuzz data bytes into fundamental and standard library types.
| static bool bslim::FuzzUtil::consumeBool | ( | FuzzDataView * | fuzzDataView | ) | [static] |
Return a bool value based upon consuming a single byte from the specified fuzzDataView. If fuzzDataView->length() is 0, return false.

| static bsl::enable_if<bsl::is_floating_point<TYPE>::value, TYPE>::type bslim::FuzzUtil::consumeNumber | ( | FuzzDataView * | fuzzDataView | ) | [static] |
Return a value of (template parameter) TYPE in the range [min .. max] -- where min and max are the minimum and maximum values representable by the TYPE -- based on at most the next sizeof(TYPE) + 1 bytes from the specified fuzzDataView, and update fuzzDataView to reflect the bytes consumed. If 0 == fuzzDataView->length(), return the minimum value of TYPE. This function does not participate in overload resolution unless either bsl::is_integral<TYPE>value or bsl::is_floating_point<TYPE>value is true. The behavior is undefined if bsl::is_same<TYPE, bool>value or bsl::is_same<TYPE, long double> is true.

| ) | [static] |
Return a value of (template parameter) TYPE in the specified range [min .. max] based on at most the next sizeof(TYPE) + 1 bytes from the specified fuzzDataView, and update fuzzDataView to reflect the bytes consumed. If 0 == fuzzDataView->length(), return the specified min. This function does not participate in overload resolution unless either bsl::is_integral<TYPE>value or bsl::is_floating_point<TYPE>value is true. The behavior is undefined if min > max, min or max is not finite, or either bsl::is_same<TYPE, bool>value or bsl::is_same<TYPE, long double> is true.

Load into the specified output a sequence of characters of length from 0 to the specified maxLength. If the specified fuzzDataView has fewer bytes than maxLength, load at most fuzzDataView->length() bytes into output. If the buffer in fuzzDataView contains two successive backslash characters, then in output they will be converted to a single backslash (\\) character; if a single backslash character is encountered, the consumption of bytes is terminated. Note that because double backslashes are mapped to single backslashes, more than maxLength bytes may be consumed from the buffer to produce the output. Also note that the purpose of this function is to enable the creation of a non-zero-terminated string_view, which is not possible with the string counterpart.

Load into the specified output a string of length from 0 to the specified maxLength. If the specified fuzzDataView has fewer bytes than maxLength, load at most fuzzDataView->length() bytes into output. If the buffer in fuzzDataView contains two successive backslash characters, then in output they will be converted to a single backslash (\\) character; if a single backslash character is encountered, the consumption of bytes is terminated. Note that because double backslashes are mapped to single backslashes, more than maxLength bytes may be consumed from the buffer to produce the output.
