b2bits::nasdaq::moldudp64::MessageBlock Class Reference

Compile-time validation of RequestPacket wire format size. More...

Detailed Description

Compile-time validation of RequestPacket wire format size.

MoldUDP64 message block header

Header preceding each individual message within a MoldUDP64 packet. The header contains only the message length, allowing variable-length messages to be packed sequentially within a packet.

Wire format (2 bytes):

• Length (2 bytes): Message length excluding this 2-byte header

The actual payload follows immediately after this header. To get the total size including the header, use get_message_length() which adds sizeof(len_) to the stored value.

Note

The length field is in network byte order (big-endian)

Length does NOT include the 2-byte header itself

Maximum message payload is 65535 bytes

Constructor & Destructor Documentation

MessageBlock() [1/2]

b2bits::nasdaq::moldudp64::MessageBlock::MessageBlock ( )

default

Default constructor.

MessageBlock() [2/2]

b2bits::nasdaq::moldudp64::MessageBlock::MessageBlock ( UInt16 len )

inline

Construct with message length.

Parameters

len	Message length in host byte order

Member Function Documentation

get_message_length()

UInt16 b2bits::nasdaq::moldudp64::MessageBlock::get_message_length ( ) const

inline

Get total message size including header.

Returns the complete message size including this 2-byte header. This is the size needed to iterate to the next message in a packet.

Returns

Total message size (payload + 2-byte header) in host byte order

Referenced by b2bits::nasdaq::moldudp64::SequencerImpl::clone().

set_message_length()

void b2bits::nasdaq::moldudp64::MessageBlock::set_message_length ( UInt16 val )

inline

Set message length.

Sets the message payload length. The value is automatically adjusted to exclude the header size before storage.

Parameters

val	Total message size (including 2-byte header) in host byte order
