//! TradingClient Creation Example
|
||
//!
|
||
//! This example demonstrates two ways to create a TradingClient:
|
||
//!
|
||
//! 1. Simple method: `TradingClient::new()` - creates client with its own infrastructure
|
||
//! 2. Shared method: `TradingClient::from_infrastructure()` - reuses existing infrastructure
|
||
//!
|
||
//! For multi-wallet scenarios, see the `shared_infrastructure` example.
