Struct zebrad::components::inbound::Inbound
source · pub struct Inbound {
setup: Setup,
}Expand description
Uses the node state to respond to inbound peer requests.
This service, wrapped in appropriate middleware, is passed to
zebra_network::init to respond to inbound peer requests.
The Inbound service is responsible for:
- supplying network data like peer addresses to other nodes;
- supplying chain data like blocks to other nodes;
- supplying mempool transactions to other nodes;
- receiving gossiped transactions; and
- receiving gossiped blocks.
Because the Inbound service is responsible for participating in the gossip
protocols used for transaction and block diffusion, there is a potential
overlap with the ChainSync and Mempool components.
The division of responsibility is that:
The ChainSync and Mempool components are internally driven,
periodically polling the network to check for new blocks or transactions.
The Inbound service is externally driven, responding to block gossip
by attempting to download and validate advertised blocks.
Gossiped transactions are forwarded to the mempool downloader, which unifies polled and gossiped transactions into a single download list.
Fields§
§setup: SetupProvides service dependencies, if they are available.
Some services are unavailable until Zebra has completed setup.
Implementations§
source§impl Inbound
impl Inbound
sourcepub fn new(
full_verify_concurrency_limit: usize,
setup: Receiver<InboundSetupData>
) -> Inbound
pub fn new( full_verify_concurrency_limit: usize, setup: Receiver<InboundSetupData> ) -> Inbound
Create a new inbound service.
Dependent services are sent via the setup channel after initialization.
sourcefn take_setup(&mut self) -> Setup
fn take_setup(&mut self) -> Setup
Remove self.setup, temporarily replacing it with an invalid state.
Trait Implementations§

impl Service<Request> for Inbound
source§fn call(&mut self, req: Request) -> Self::Future
fn call(&mut self, req: Request) -> Self::Future
Call the inbound service.
Errors indicate that the peer has done something wrong or unexpected, and will cause callers to disconnect from the remote peer.
