This PR brings an option to disable
thiserror::v1
when using C++20.The
v1
is now disabled by default on C++20 because I think most users do not want to use an extra dependency (Boost.Metaparse
). When we want to keepv1
, we can enable it by definingMITAMA_THISERROR_ENABLE_V1
like#define MITAMA_THISERROR_ENABLE_V1 true
.
