}

Local configuration for one side of a Caller-Listener handshake — the values this engine advertises (draft-sharabayko-srt-01 §3.2.1, §3.2.1.1, §3.2.1.3, §3.2.1.4).

Fields

latency_ms: u16

TSBPD delay in milliseconds this side requests, sent as both the Receiver and Sender TSBPD Delay of its Handshake Extension Message (§3.2.1.1, Figure 6). The negotiated value is the greater of the two parties’ requests (§4.3.1.2).

mtu: u32

Maximum Transmission Unit Size (§3.2.1).

max_flow_window_size: u32

Maximum Flow Window Size (§3.2.1).

initial_seq_number: u32

Initial Packet Sequence Number this side will use for its first data packet (§3.2.1). No data plane exists yet in this crate; callers of a later data-plane PR are expected to set this to a real ISN.

srt_version: u32

The SRT Version this side reports in its Handshake Extension Message (major * 0x10000 + minor * 0x100 + patch, §3.2.1.1).

flags: HandshakeExtensionMessageFlags

SRT Flags this side advertises (§3.2.1.1.1, Table 6).

encryption_field: EncryptionField

Advertised cipher family and block size (§3.2.1, Table 2). Actual key-wrap/unwrap crypto is an explicit follow-up; this field is negotiated but not acted on in this release.

stream_id: Option<String>

Stream ID to advertise (Caller only — §3.2.1.3); None sends no Stream ID extension.

group: Option<GroupMembershipExtension>

Group Membership to advertise (§3.2.1.4); None sends no Group extension.

local_ip: [u32; 4]

This side’s own IP address, reported in every outgoing handshake packet’s Peer IP Address field (§3.2.1: “IPv4 or IPv6 address of the packet’s sender” — despite the field’s name, each party reports its own address, not its peer’s).

retransmit_after_ticks: u32

Number of crate::caller::CallerHandshake::tick / crate::listener::ListenerHandshake::tick calls with no reply before the last-sent handshake packet is retransmitted. Timeouts are modeled as caller-driven ticks — no wall-clock lives in this crate.

max_retries: u32

Maximum number of retransmissions before the handshake gives up (HandshakeOutput::TimedOut).

crypto: Option<CryptoConfig>

Available on crate feature crypto only.

Opt-in §6 payload-encryption negotiation (crypto feature only). None (the default) means this side neither offers nor requires encryption. See CryptoConfig for the caller-supplied Salt/SEK contract.
