Utils/Bits

Bit manipulation, fast serialization buffers, and hashing support used by the ecosystem's hash maps.

Main features

• Fast write-oriented bit buffer: booleans, integers, arrays, doubles, floats, padded strings (CBitBuffer in BitFastBuffer.mqh).
• Little-endian / big-endian byte (de)serialization (FromBytesLE, FromBytesBE, ToBytes).
• Generic hash + equality implementation for CBitBuffer, so it can be used as a key in TSN hash maps (TSN::CGenericHash_CBitBuffer in Hash.mqh, built on XXH64).

Basic usage

CBitBuffer bit;
bit.WriteBool(true);
bit.WriteInteger(42);
bit.WriteDouble(3.14);

uchar buf[];
int written = bit.ToBytes(buf);

// Using CBitBuffer as a hash map key:
TSN::CHashMapFastNor<TSN::CBitBuffer, int, TSN::CGenericHash_CBitBuffer> cache;

Only the most representative methods are shown here.
