Crate actpub_axum

Expand description

axum 0.8 integration for actpub-federation.

Drop-in router builders that wire the federation runtime into an existing axum service:

inbox_router — POST endpoint dispatching to a configured InboxPipeline.
webfinger_router — /.well-known/webfinger endpoint resolving acct: URIs via a user-supplied callback.
nodeinfo_router — /.well-known/nodeinfo discovery + per-version schema endpoints.
FederationJson<T> responder — serialises T with the application/activity+json media type required by every Fediverse peer.

Each router is a standalone Router that mounts at its conventional path; compose them via Router::merge to build a complete service.

Structs§

FederationJson: JSON responder that emits the federation-mandated Content-Type.
InboxState: Shared state handed to the inbox handler.
NodeInfoState: Shared state for the NodeInfo router.

ACTIVITY_PUB_CONTENT_TYPE: Wire-mandated Content-Type for ActivityPub JSON responses.
DEFAULT_MAX_INBOX_BYTES: Default inbox body cap (1 MiB) — large enough for any realistic activity, small enough to bound memory under hostile load.
JRD_CONTENT_TYPE: Content-Type mandated by RFC 7033 §10.2 for JRD responses.
NODEINFO_CONTENT_TYPE: Content-Type Mastodon and most Fediverse peers send for NodeInfo documents (matches what nodeinfo.diaspora.software recommends).

WebFingerResolver: Asynchronous callback that resolves a ?resource=<uri> query into a Jrd describing it.

inbox_router: Builds an axum Router mounted at /inbox that POSTs into the supplied state’s pipeline.
nodeinfo_router: Builds the NodeInfo router.
webfinger_router: Builds the /.well-known/webfinger router.
