Struct ServerBuilder 

pub struct ServerBuilder<S> { /* private fields */ }

A builder for configuring and launching multiple RPC servers from a single service implementation.

This provides a fluent interface to add different protocol servers that all delegate to the same shared service logic.

Implementations

impl<S> ServerBuilder<S>

where S: Send + Sync + 'static,

pub fn new(service: S) -> Self

Creates a new ServerBuilder.

Arguments

• service - The service implementation that will be shared across all protocols.

pub fn add_protocol<F>(self, factory: F) -> Self

where F: FnOnce(Arc<S>) -> ServerTask + Send + 'static,

Adds a protocol server to the builder.

The #[multi_rpc_impl] macro generates protocol-specific factory functions (e.g., greeter_impls::tarpc_tcp(...)) that can be passed to this method.

Arguments

• factory - A function that takes the shared service instance and returns a future representing the running server task.

pub fn build(self) -> Result<ServerRunner, Error>

Consumes the builder, spawning all configured protocol servers on the Tokio runtime.

Returns a ServerRunner which can be used to keep the application alive until a shutdown signal is received.
