Function ruma::state_res::auth_check

pub fn auth_check<E>(
    room_version: &RoomVersion, 
    incoming_event: &Arc<E>, 
    prev_event: Option<Arc<E>>, 
    auth_events: &BTreeMap<(EventType, String), Arc<E>>, 
    current_third_party_invite: Option<Arc<E>>
) -> Result<bool, Error> where
    E: Event, 

This is supported on crate feature state-res only.

Authenticate the incoming event. The steps of authentication are:

• check that the event is being authenticated for the correct room
• check that the events signatures are valid
• then there are checks for specific event types

The auth_events that are passed to this function should be a state snapshot. We need to know if the event passes auth against some state not a recursive collection of auth_events fields.

Returns

This returns an Error only when serialization fails or some other fatal outcome.
