Enum documentation

enum scn::v3::scan_error::code

Error code.

Enumerators
good

No error.
end_of_range

EOF.
invalid_format_string

Format string was invalid.
invalid_scanned_value

Scanned value was invalid for given type. e.g. a period '.' when scanning for an int
value_out_of_range

Scanned value was out of range for the desired type. (e.g. >2^32 for an uint32_t)
max_error
