[−][src]Struct abi_stable::std_types::std_error::RBoxError_
Ffi-safe version of Box<::std::error::Error+'static>
whose Send+Syncness is determined by the M type parameter.
It cannot be converted back to Box<::std::error::Error>,
requiring wrapping RBoxError_<_> itself to be wrapped in a Box<_>.
Unwrapping a Box<Error+?Send+?Sync+'static> back to
RBoxError_<_> does not incurr an allocation.
