pub struct NetworkService { /* fields omitted */ }

IO Service with networking Message defines a notification data type.

Implementations

impl NetworkService

pub fn new(
    config: NetworkConfiguration,
    filter: Option<Arc<dyn ConnectionFilter>>
) -> Result<NetworkService, Error>

Starts IO event loop

pub fn register_protocol(
    &self,
    handler: Arc<dyn NetworkProtocolHandler + Send + Sync>,
    protocol: ProtocolId,
    versions: &[(u8, u8)]
) -> Result<(), Error>

Register a new protocol handler with the event loop.

pub fn host_info(&self) -> String

Returns host identifier string as advertised to other peers

pub fn io(&self) -> &IoService<NetworkIoMessage>

Returns underlying io service.

pub fn num_peers_range(&self) -> RangeInclusive<u32>

Returns the number of peers allowed.

pub fn external_url(&self) -> Option<String>

Returns external url if available.

pub fn local_url(&self) -> Option<String>

Returns external url if available.

pub fn start(&self) -> Result<(), (Error, Option<SocketAddr>)>

Start network IO.

In case of error, also returns the listening address for better error reporting.

pub fn stop(&self)

Stop network IO.

pub fn connected_peers(&self) -> Vec<PeerId>

pub fn remove_reserved_peer(&self, peer: &str) -> Result<(), Error>

Try to remove a reserved peer.

pub fn set_non_reserved_mode(&self, mode: NonReservedPeerMode)

Set the non-reserved peer mode.

pub fn with_context<F>(&self, protocol: ProtocolId, action: F) where
    F: FnOnce(&dyn NetworkContext), 

Executes action in the network context

pub fn with_context_eval<F, T>(
    &self,
    protocol: ProtocolId,
    action: F
) -> Option<T> where
    F: FnOnce(&dyn NetworkContext) -> T, 

Evaluates function in the network context
