std::pair< iterator, bool > try_emplace(KeyT &&Key, Ts &&...Args)
Tagged union holding either a T or a Error.
Error takeError()
Take ownership of the stored error.
The instances of the Type class are immutable: once they are created, they are never changed.
Iterator at(uint32_t Offset) const
given an offset into the array's underlying stream, return an iterator to the record at that offset.
