Struct ServiceClient 

pub struct ServiceClient { /* private fields */ }

Standalone client for calling microservices from external applications

This is perfect for:

• API Gateway calling microservices
• Testing microservices
• Integration between different systems

Implementations

impl ServiceClient

pub async fn new( client_name: impl Into<String>, amqp_url: impl Into<String>, ) -> Result<Self>

Create a new service client

pub async fn call( &self, service: impl Into<String>, method: impl Into<String>, params: impl Serialize, ) -> Result<RpcResponse>

Call a microservice method

This is how the API gateway calls microservices:

let client = ServiceClient::new("api-gateway", "amqp://localhost:5672").await?;
let response = client.call("user-service", "get_user", 123).await?;

pub async fn call_with_timeout( &self, service: impl Into<String>, method: impl Into<String>, params: impl Serialize, timeout: Duration, ) -> Result<RpcResponse>

Call with custom timeout

pub async fn is_healthy(&self) -> bool

Check if client is connected and healthy

pub async fn get_stats(&self) -> ClientStats

Get client statistics
