Struct RuntimeTransportContract 

pub struct RuntimeTransportContract {
    pub transport_name: String,
    pub transport_type: String,
    pub role_addressed_routing: bool,
    pub authenticated_peers: bool,
    pub per_peer_fifo_delivery: bool,
    pub fail_closed_unknown_role: bool,
    pub no_message_synthesis: bool,
    pub explicit_readiness_errors: bool,
    pub deterministic_for_regression: bool,
}

Machine-side summary of a selected transport contract.

This is semantic evidence, not a transport implementation hook. Concrete transport crates translate their selected authentication, routing, and delivery mode into these fields; telltale-machine only checks whether the selected runtime path satisfies the theorem-pack assumptions. That keeps the machine independent of TCP, TLS, pre-shared keys, or any other concrete authentication mechanism.

Fields

transport_name: String

Stable transport/profile name.

transport_type: String

Human-readable transport kind, e.g. InMemory or Tcp.

role_addressed_routing: bool

Whether messages are routed by role identity.

authenticated_peers: bool

Whether peer identity is authenticated at the transport boundary.

This must be false for trusted-network-only transports. Theorem packs that depend on protocol-origin integrity require this field to be true.

per_peer_fifo_delivery: bool

Whether each peer stream preserves FIFO delivery.

fail_closed_unknown_role: bool

Whether unknown role claims are rejected instead of admitted.

no_message_synthesis: bool

Whether the transport can synthesize messages not sent by a peer.

explicit_readiness_errors: bool

Whether startup/readiness failures are surfaced explicitly.

deterministic_for_regression: bool

Whether the transport is deterministic enough for regression harnesses.

Implementations

impl RuntimeTransportContract

pub fn new( transport_name: impl Into<String>, transport_type: impl Into<String>, ) -> Self

Start a semantic transport contract summary.

All semantic fields default to false so callers must opt in to each contract they can justify for the selected runtime transport.

pub fn first_party_in_memory() -> Self

Contract summary for the first-party in-process channel transport.

pub fn with_role_addressed_routing(self, value: bool) -> Self

Set whether messages are routed by role identity.

pub fn with_authenticated_peers(self, value: bool) -> Self

Set whether peer identity is authenticated at the transport boundary.

Set this to true only when the selected transport mode cryptographically or otherwise operationally binds a peer to its claimed role. Plain TCP on a trusted network should leave this false.

pub fn with_per_peer_fifo_delivery(self, value: bool) -> Self

Set whether each peer stream preserves FIFO delivery.

pub fn with_fail_closed_unknown_role(self, value: bool) -> Self

Set whether unknown role claims are rejected instead of admitted.

pub fn with_no_message_synthesis(self, value: bool) -> Self

Set whether the transport can synthesize messages not sent by a peer.

pub fn with_explicit_readiness_errors(self, value: bool) -> Self

Set whether startup/readiness failures are surfaced explicitly.

pub fn with_deterministic_for_regression(self, value: bool) -> Self

Set whether the transport is deterministic enough for regression harnesses.

Trait Implementations

impl Clone for RuntimeTransportContract

fn clone(&self) -> RuntimeTransportContract

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RuntimeTransportContract

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RuntimeTransportContract

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RuntimeTransportContract

fn eq(&self, other: &RuntimeTransportContract) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for RuntimeTransportContract

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
