Struct TcpConversationState 

pub struct TcpConversationState {
    pub conn_state: TcpConnectionState,
    pub forward_endpoint: TcpEndpointState,
    pub reverse_endpoint: TcpEndpointState,
    pub reassembler_fwd: TcpReassembler,
    pub reassembler_rev: TcpReassembler,
    pub dropped_segments_fwd: u64,
    pub dropped_segments_rev: u64,
}

Complete TCP conversation state including connection tracking, per-endpoint sequence state, and stream reassembly.

Fields

conn_state: TcpConnectionState

Current connection state (RFC 793 state machine).

forward_endpoint: TcpEndpointState

Sequence tracking for the forward direction (addr_a → addr_b).

reverse_endpoint: TcpEndpointState

Sequence tracking for the reverse direction (addr_b → addr_a).

reassembler_fwd: TcpReassembler

Stream reassembly for forward direction.

reassembler_rev: TcpReassembler

Stream reassembly for reverse direction.

dropped_segments_fwd: u64

Number of forward segments dropped due to buffer/fragment limits.

dropped_segments_rev: u64

Number of reverse segments dropped due to buffer/fragment limits.

Implementations

impl TcpConversationState

pub fn new() -> Self

pub fn total_dropped_segments(&self) -> u64

Total dropped segments across both directions.

pub fn process_packet( &mut self, direction: FlowDirection, tcp: &TcpLayer, buf: &[u8], config: &FlowConfig, ) -> Result<(), FlowError>

Process a TCP packet, updating connection state and reassembly buffers.

direction indicates whether this packet is Forward (addr_a → addr_b) or Reverse (addr_b → addr_a) relative to the canonical key. tcp is the TCP layer view, buf is the full packet buffer.

Trait Implementations

impl Debug for TcpConversationState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TcpConversationState

fn default() -> Self

Returns the “default value” for a type.
