RoNodeMethods should have conditional noexcept #389
Description
Throwing error callback
c4::yml::set_callbacks({ nullptr, nullptr, nullptr, [](const char*, std::size_t, c4::yml::Location, void*){ throw 42; } });
may lead to abort() in that case
ryml::ConstNodeRef node = Tree.rootref();
c4::csubstr invalidName = /*...*/;
node[invalidName];
bacuse noexcept operator[] calls this callback
C4_ALWAYS_INLINE C4_PURE ConstImpl operator[] (csubstr k) const noexcept
{
_C4RV();
size_t ch = tree_->find_child(id_, k);
_RYML_CB_ASSERT(tree_->m_callbacks, ch != NONE);
return {tree_, ch};
}
I saw you mentioned that I can't return from error callback, so basically I can either call abort() or throw an exception, which in turn also leads to abort(). Config parsing error is an expected scenario in my case. So I'd like to handle such errors(even in debug build), rather than crashing the whole app
