Detailed Description

template<size_t kMaxSizeBytes>
class pw::tokenizer::EncodedMessage< kMaxSizeBytes >

Encodes a tokenized message to a fixed size buffer. This class is used to encode tokenized messages passed in from tokenization macros.

To use pw::tokenizer::EncodedMessage, construct it with the token, argument types, and va_list from the variadic arguments:

void SendLogMessage(span<std::byte> log_data);
 
extern "C" void TokenizeToSendLogMessage(pw_tokenizer_Token token,
                                         pw_tokenizer_ArgTypes types,
                                         ...) {
  va_list args;
  va_start(args, types);
  EncodedMessage encoded_message(token, types, args);
  va_end(args);
 
  SendLogMessage(encoded_message);  // EncodedMessage converts to span
}
