Struct ServerBuilder

pub struct ServerBuilder<M: Metadata = (), S: Middleware<M> = NoopMiddleware> { /* private fields */ }

Convenient JSON-RPC HTTP Server builder.

Implementations

impl<M: Metadata, S: Middleware<M>> ServerBuilder<M, S>

pub fn new<T>(handler: T) -> Self

where T: Into<MetaIoHandler<M, S>>,

Creates new ServerBuilder for given IoHandler.

If you want to re-use the same handler in couple places see with_remote function.

By default:

1. Server is not sending any CORS headers.
2. Server is validating Host header.

pub fn event_loop_remote(self, remote: Remote) -> Self

Utilize existing event loop remote to poll RPC results. Applies only to 1 of the threads. Other threads will spawn their own Event Loops.

pub fn keep_alive(self, val: bool) -> Self

Sets Enables or disables HTTP keep-alive. Default is true.

pub fn threads(self, threads: usize) -> Self

Sets number of threads of the server to run. Panics when set to 0.

pub fn cors( self, cors_domains: DomainsValidation<AccessControlAllowOrigin>, ) -> Self

Configures a list of allowed CORS origins.

pub fn request_middleware<T: RequestMiddleware>(self, middleware: T) -> Self

Configures request middleware

pub fn meta_extractor<T: MetaExtractor<M>>(self, extractor: T) -> Self

Configures metadata extractor

pub fn allow_only_bind_host(self) -> Self

Allow connections only with Host header set to binding address.

pub fn allowed_hosts(self, allowed_hosts: DomainsValidation<Host>) -> Self

Specify a list of valid Host headers. Binding address is allowed automatically.

pub fn start_http(self, addr: &SocketAddr) -> ServerResult

Start this JSON-RPC HTTP server trying to bind to specified SocketAddr.
