scan_error class
Error class. Used as a return value for functions without a success value. Doesn't have a success state, and isn't default constructible: use expected<void, scan_ to achieve that.

Error code.
| Enumerators | |
|---|---|
| end_of_input |
Input ended unexpectedly. |
| invalid_format_string |
Format string was invalid. Often a compile-time error, if supported or enabled. |
| invalid_scanned_value |
Scanned value was invalid for given type, or a value of the given couldn't be scanned. |
| invalid_literal |
Literal character specified in format string not found in source. |
| invalid_fill |
Too many fill characters scanned, field precision (max width) exceeded. |
| length_too_short |
Scanned field width was shorter than what was specified as the minimum field width. |
| invalid_source_state |
Source range is in an invalid state, failed to continue reading. |
| value_positive_overflow |
Value out of range, too large (higher than the maximum value) i.e. >2^32 for int32 |
| value_negative_overflow |
Value out of range, too small (lower than the minimum value) i.e. <2^32 for int32 |
| value_positive_underflow |
Value out of range, magnitude too small, sign + (between 0 and the smallest subnormal float) |
| value_negative_underflow |
Value out of range, magnitude too small, sign - (between 0 and the smallest subnormal float) |
| max_error |
