Crate m4a_matrix_core 

Matrix event layer, spike stage (F3.0).

What it does: builds room events of room version 11 the way a foreign Matrix server expects them: no event_id on the wire, a content hash, an ed25519 signature over the redacted form, and an event id that is COMPUTED ($ + url-safe unpadded base64 of the reference hash). It checks every new event against the room’s auth rules before accepting it, and wraps ruma-state-res for state resolution over forked state.

What it is not: no HTTP, no storage, no federation transport. Keys come in through a closure, so the crate does not care which ed25519 implementation the caller uses. All ruma types stay behind this crate’s own small surface.

Modules

dag

The event DAG of one room, over any store that can answer DagRead.

Structs

EventId

A Matrix event ID.

OwnedEventId

Owned variant of EventId.

OwnedRoomId

Owned variant of RoomId.

OwnedUserId

Owned variant of UserId.

Pdu

A persistent data unit with the fields state resolution and the auth rules read.

RoomBuilder

Builds the timeline of one NEW room, event by event: fills prev_events, depth and the auth_events the spec selects from the current state, hashes and signs, computes the id, and refuses an event the auth rules would reject.

RoomVersionRules

The rules applied to a room version.

SignedEvent

A finished event: its computed id and the signed wire JSON (no event_id inside).

Signer

An ed25519 signer: server name, key id (ed25519:<version>) and a signing closure. The closure signs the exact bytes it is given and returns the 64-byte signature.

Enums

BuildError

CanonicalJsonValue

Represents a canonical JSON value as per the Matrix specification.

IdError

An error encountered when trying to parse an invalid ID string.

ResolveError

RoomVersionId

A Matrix room version ID.

StateEventType

The type of StateEvent this is.

Constants

ROOM_VERSION

The room version this spike emits.

Functions

auth_chain

The full recursive set of auth events of ids (the ids themselves included).

auth_chain_with

auth_chain over any event source.

key_from_b64

A signing key as ruma wants it, from standard base64 (padded or not).

key_to_b64

Standard base64 of public key bytes.

resolve_state

Resolves forked room states (state resolution v2) over a set of known events.

resolve_state_with

resolve_state over any event source (a store lookup).

Type Aliases

CanonicalJsonObject

The inner type of CanonicalJsonValue::Object.

PublicKeyMap

A map from entity names to sets of public keys for that entity.

StateMap

A mapping of event type and state_key to some value T, usually an EventId.
