Attribute Macro rpc 

#[rpc]

Blessed preset: JSON-RPC server with OpenRPC spec and serve.

Combines #[jsonrpc] + #[openrpc] + #[serve(jsonrpc)] into a single attribute. OpenRPC and serve are included when their features are enabled, and gracefully omitted otherwise.

Example

use server_less::rpc;

#[derive(Clone)]
struct Calculator;

#[rpc]
impl Calculator {
    pub fn add(&self, a: i32, b: i32) -> i32 { a + b }
    pub fn multiply(&self, a: i32, b: i32) -> i32 { a * b }
}

Options

• path - JSON-RPC endpoint path (e.g., #[rpc(path = "/api")])
• openrpc - Toggle OpenRPC spec generation (default: true)
• health - Custom health check path (default: /health)
