Detailed Description

The cause of the failure of an operation in LLFIO.

Member Function Documentation

message()

std::string llfio_v2_xxx::error_info::message ( ) const

inline

Retrieve a descriptive message for this failure, possibly with paths and stack backtraces. Extra detail only appears if called from the same thread as where the failure occurred.

  {
    std::string ret(ec.message());
#if !LLFIO_DISABLE_PATHS_IN_FAILURE_INFO
    detail::append_path_info(*this, ret);
#endif
    return ret;
  }

throw_exception()

void llfio_v2_xxx::error_info::throw_exception ( ) const

inline

Throw this failure as a C++ exception. Firstly if the error code matches any of the standard C++ exception types e.g. bad_alloc, we throw those types using the string from message() where possible. We then will throw an error exception type.

{
  std::string msg;
  try
  {
    msg = message();
  }
  catch(...)
  {
  }
  OUTCOME_V2_NAMESPACE::try_throw_std_exception_from_error(ec, msg);
  throw error(*this);
}
