Struct sc_authority_discovery::Service [−][src]
pub struct Service { /* fields omitted */ }
Expand description
Service to interact with the crate::Worker
.
Implementations
A Service
allows to interact with a crate::Worker
, e.g. by querying the
crate::Worker
’s local address cache for a given AuthorityId
.
Get the addresses for the given AuthorityId
from the local address
cache.
Returns None
if no entry was present or connection to the
crate::Worker
failed.
Note: [Multiaddr
]s returned always include a [PeerId
] via a
[libp2p::core::multiaddr::Protocol::P2p
] component. Equality of
[PeerId
]s across [Multiaddr
]s returned by a single call is not
enforced today, given that there are still authorities out there
publishing the addresses of their sentry nodes on the DHT. In the future
this guarantee can be provided.
Get the AuthorityId
for the given [PeerId
] from the local address
cache.
Returns None
if no entry was present or connection to the
crate::Worker
failed.
