rusty_feeder::session_manager

Struct SessionManager

Source 
pub struct SessionManager<T: Clone + DeserializeOwned, const N: usize = 8> { /* private fields */ }
Expand description

Session manager for handling multiple concurrent connections to exchanges with failover, load balancing, and session persistence.

§Type Parameters

  • T: Message type that the session manager handles
  • N: Maximum number of concurrent sessions (default: 8) Optimized for typical HFT scenarios with multiple exchange connections
