scanner::parse now returns Iterator, not scan_expected<Iterator>
Errors are reported by throwing a scan_format_string_error, or by calling ParseContext::on_error.
Optimize the way scan calls vscan to remove extra copies/moves
:::cpp
// Dummy-implementation of scan
// Before (v3):
auto args = make_scan_args<scan_context, Args...>();
auto result = vscan(std::forward(source), format, args);
return make_scan_result(std::move(result), std::move(args.args()));
// Now (v4):
auto result = make_scan_result<Source, Args...>();
fill_scan_result(result, vscan(std::forward(source), format,
make_scan_args(result->values())));
return result;
* Changes to scan_error
* Success state removed: use expected<void, scan_error> instead.
* scan_error::value_out_of_range split into value_positive_overflow, value_negative_overflow,
value_positive_underflow, and value_negative_overflow.
* end_of_range renamed to end_of_input.
* invalid_literal, invalid_fill, length_too_short, and invalid_source_state added.
* basic_scan_context is now templated on the range type
Features
<chrono> scanning
Scanning of pointers (void* and const void*)
Ability to disable dependency on FastFloat with SCN_DISABLE_FAST_FLOAT
FastFloat used to be the only required external dependency
If disabled, std::from_chars for floating-point values is required
