ParseResult

template<typename T, typename InputIt>
struct ParseResult

Result of a parsing operation.

Template Parameters:

• T – The type of the parsed value.

• InputIt – The input iterator type.

Public Members

T parsed_value

The value obtained from parsing the input.

InputIt ptr

Iterator pointing to the remaining unparsed input.

Examples

#include <chesscxx/parse.h>
#include <chesscxx/square.h>

#include <iterator>
#include <print>
#include <string_view>

auto main() -> int {
  std::string_view const input = "e4 extra input";

  auto result =
      chesscxx::parseFrom<chesscxx::Square>(input.begin(), input.end());
  if (!result) return 1;

  std::println("{}", result.value().parsed_value);
  std::println("{}", result.value().ptr);
  std::println("{}", std::distance(input.begin(), result.value().ptr) == 2);
}

Output:

e4
 extra input
true
