Struct NodeService 

pub struct NodeService<C>
where
    C: ClientContext + 'static,
{ /* private fields */ }

The NodeService is a server that exposes a web-server to the client. The node service is primarily used to explore the state of a chain in GraphQL.

Implementations

impl<C> NodeService<C>

where C: ClientContext,

pub fn new( config: ChainListenerConfig, port: NonZeroU16, default_chain: Option<ChainId>, context: Arc<Mutex<C>>, read_only: bool, query_cache_size: Option<usize>, query_subscriptions: Option<Arc<QuerySubscriptionManager>>, cancellation_token: CancellationToken, enable_memory_profiling: bool, pause: bool, ) -> Self

Creates a new instance of the node service given a client chain and a port.

query_cache_size controls the per-chain LRU cache capacity for application query responses. Pass None to disable the cache (the default). Enable with --query-cache-size <N>. Incompatible with --long-lived-services.

pub fn schema(&self) -> NodeServiceSchema<C>

Builds the GraphQL schema served by the node service.

pub async fn run( self, cancellation_token: CancellationToken, command_receiver: UnboundedReceiver<ListenerCommand>, ) -> Result<(), Error>

Runs the node service.

Trait Implementations

impl<C> Clone for NodeService<C>

where C: ClientContext + 'static,

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
