Struct InMemoryHandler 

pub struct InMemoryHandler {
    pub local: Option<String>,
    pub peer: Option<String>,
}

A simulated transport that authenticates a fixed local-and-peer VID pair.

On the consumer side it reports the configured peer as the transport-authenticated issuer and the configured local party as the transport-authenticated recipient. On the producer side it strips in-band members that match the configured local-as-issuer / peer-as-recipient assignment — modelling the §9.2 item 1 behavior of a transport that conveys authenticated identity end-to-end.

Use it for tests and examples that want to exercise the TransportHandler contract without standing up a real binding.

Fields

local: Option<String>

Authenticated identity of the party running this handler.

peer: Option<String>

Authenticated identity of the peer this handler is talking to.

Implementations

impl InMemoryHandler

pub fn new() -> InMemoryHandler

Construct a handler with no configured parties (equivalent to NoopHandler for consumer-side resolution).

pub fn with_local(self, vid: impl Into<String>) -> InMemoryHandler

Set the local party identity. Builder-style.

pub fn with_peer(self, vid: impl Into<String>) -> InMemoryHandler

Set the peer party identity. Builder-style.

Trait Implementations

impl Clone for InMemoryHandler

fn clone(&self) -> InMemoryHandler

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InMemoryHandler

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

Formats the value using the given formatter.

impl Default for InMemoryHandler

fn default() -> InMemoryHandler

Returns the “default value” for a type.

impl TransportHandler for InMemoryHandler

fn binding_uri(&self) -> &str

A stable identifier for this transport binding, suitable for logs and audit (SPEC.md §9.1, §9.2 — “A transport binding specification SHOULD identify itself by a stable URI”).

fn derive_parties(&self) -> TransportContext

Identities the transport authenticated for the inbound message under consideration.

fn prepare_outbound<P>(&self, doc: &mut TrustTask<P>)

where P: Serialize,

Prepare an outbound document for emission over this transport.

fn resolve_parties<P>( &self, doc: &TrustTask<P>, ) -> Result<ResolvedParties, ConsistencyError>

Apply SPEC.md §4.8.1 precedence to produce the final ResolvedParties for an inbound document.

fn reject<P>( &self, doc: &TrustTask<P>, id: impl Into<String>, reason: RejectReason, ) -> Option<TrustTask<ErrorPayload>>

Build a trust-task-error response for doc that satisfies the SPEC.md §8.1 routing rules — most importantly, the rule that under RejectReason::IdentityMismatch the error MUST address the transport-authenticated sender and MUST NOT address the contested in-band issuer.
