codecs::basic_codec::lazy_decode

template <typename T = traits::default_decoded_output>
static /* unspecified */ lazy_decode();

Returns a function object that decodes input.

---

The returned function object has the same constraints as codecs::basic_codec::decode.

Example

#include <mgs/base64.hpp>
#include <mgs/codecs/basic_codec.hpp>
#include <mgs/codecs/iterator_sentinel_source.hpp>

using namespace mgs;
using namespace mgs::codecs;

using codec = basic_codec<base64::traits>;

int main() {
  std::string encoded("SGVsbG8sIFdvcmxkIQ==");
  auto input_source = make_iterator_sentinel_source(encoded);

  codec::lazy_decode()(input_source);
  codec::lazy_decode()(encoded.begin(), encoded.end());
  codec::lazy_decode()(encoded);
  codec::lazy_decode()(std::move(encoded));
}
