Implementations

impl<Req, Res> DatabaseReadService<Req, Res>

where Req: Send + 'static, Res: Send + 'static,

pub fn new( env: Arc<ConcreteEnv>, pool: Arc<ThreadPool>, req_handler: impl Fn(&ConcreteEnv, Req) -> Result<Res, RuntimeError> + Send + Sync + 'static, ) -> DatabaseReadService<Req, Res>

Creates the DatabaseReadService with the provided backing thread-pool.

Should be called once per actual database, although nothing bad will happen, cloning the DatabaseReadService is the correct way to get multiple handles to the database.

Trait Implementations

impl<Req, Res> Clone for DatabaseReadService<Req, Res>

fn clone(&self) -> DatabaseReadService<Req, Res>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Req, Res> Service<Req> for DatabaseReadService<Req, Res>

where Req: Send + 'static, Res: Send + 'static,

type Response = Res

Responses given by the service.

type Error = RuntimeError

Errors produced by the service.

type Future = InfallibleOneshotReceiver<Result<<DatabaseReadService<Req, Res> as Service<Req>>::Response, RuntimeError>>

The future response value.

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

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

fn call( &mut self, req: Req, ) -> <DatabaseReadService<Req, Res> as Service<Req>>::Future

Process the request and return the response asynchronously.
