Module transport 

Transports and address resolution.

A Transport carries a message into a mailbox and is registered as an SCXML Event I/O Processor under its type IRI, which <send type="..."> selects; the runtime lists every registered transport in _ioprocessors. M2 ships the in-process LocalTransport.

The Directory maps an address to the mailbox that serves it. Addresses hosted on this node are resolved first; any other address goes to the Resolver registered for its IRI scheme. Resolution depends only on the address.

Structs

Directory

The resolvers of non-local addresses, keyed by IRI scheme.

The in-process transport: the SCXML Event I/O Processor (http://www.w3.org/TR/scxml/#SCXMLEventProcessor, alias scxml).

ResolveError

An address the directory could not resolve.

TransportError

A delivery failure; the outbox keeps the send and retries it.

The registered transports, by type IRI and alias.

Traits

Resolver

Transport

The transport contract: an SCXML Event I/O Processor that delivers into mailboxes.
