template<>
class HEEncoder<Scheme::BFV> HEEncoder is responsible for encoding messages into plaintexts suitable for homomorphic encryption.
The HEEncoder class is initialized with encryption parameters and provides methods to encode different types of messages (e.g., integers, floating-point numbers, complex numbers) into plaintexts for BFV and CKKS schemes. The class supports both synchronous and asynchronous encoding operations, making it suitable for different homomorphic encryption workflows.
