Struct GraphNodeService 

pub struct GraphNodeService<S, B, Input>
where
    S: Service<Task<Input>>,
    B: Backend,
{ /* private fields */ }

A service that wraps another service to handle encoding and decoding of task inputs and outputs using the backend’s codec.

Implementations

impl<S, B, Input> GraphNodeService<S, B, Input>

where S: Service<Task<Input>>, B: Backend,

pub fn new(inner: S) -> Self

Creates a new NodeService wrapping the provided service.

Trait Implementations

impl<S, B, Input> Clone for GraphNodeService<S, B, Input>

where S: Service<Task<Input>> + Clone, B: Backend,

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S, B, Input> Debug for GraphNodeService<S, B, Input>

where S: Service<Task<Input>>, B: Backend,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<S, B, Input, CdcErr> Service<Task<NodeInput<<B as WireFormatBackend>::Compact>>> for GraphNodeService<S, B, Input>

where S: Service<Task<Input>>, S::Error: Into<BoxDynError>, B: Backend + WireFormatBackend + BackendConfig + Send + Sync + 'static, B::Codec: Codec<Input, Compact = B::Compact, Error = CdcErr> + Codec<S::Response, Compact = B::Compact, Error = CdcErr> + Send + Sync + Clone, Input: GraphCodec<B, Error = CdcErr> + DeserializeOwned, CdcErr: Into<BoxDynError> + Send + 'static, S::Future: Send + 'static, S::Response: Serialize,

type Response = (<B as WireFormatBackend>::Compact, Value)

Responses given by the service.

type Error = Box<dyn Error + Sync + Send>

Errors produced by the service.

type Future = Pin<Box<dyn Future<Output = Result<<GraphNodeService<S, B, Input> as Service<Task<NodeInput<<B as WireFormatBackend>::Compact>>>>::Response, <GraphNodeService<S, B, Input> as Service<Task<NodeInput<<B as WireFormatBackend>::Compact>>>>::Error>> + Send>>

The future response value.

fn poll_ready(&mut self, cx: &mut Context<'_>) -> Poll<Result<(), Self::Error>>

Returns Poll::Ready(Ok(())) when the service is able to process requests.

fn call(&mut self, req: Task<NodeInput<B::Compact>>) -> Self::Future

Process the request and return the response asynchronously.
