Struct TradingInfrastructure 

pub struct TradingInfrastructure {
    pub rpc: Arc<SolanaRpcClient>,
    pub swqos_clients: Arc<Vec<Arc<SwqosClient>>>,
    pub config: InfrastructureConfig,
    pub max_sender_concurrency: usize,
    pub effective_core_ids: Arc<Vec<CoreId>>,
}

Shared infrastructure components that can be reused across multiple wallets

This struct holds the expensive-to-initialize components (RPC client, SWQOS clients) that are wallet-independent and can be shared when only the trading wallet changes.

Fields

rpc: Arc<SolanaRpcClient>

Shared RPC client for blockchain interactions

swqos_clients: Arc<Vec<Arc<SwqosClient>>>

Shared SWQOS clients for transaction priority and routing. Arc<Vec<..>> so cloning into SwapParams is a single Arc clone.

config: InfrastructureConfig

Configuration used to create this infrastructure

max_sender_concurrency: usize

Precomputed at init: min(max SWQOS submit lanes, 2/3 * num_cores). Not computed on trade hot path.

effective_core_ids: Arc<Vec<CoreId>>

Precomputed at init: first max_sender_concurrency CoreIds for job affinity. Empty if no cores. Not computed on trade hot path.

Implementations

impl TradingInfrastructure

pub async fn new(config: InfrastructureConfig) -> Self

Create new shared infrastructure from configuration

This performs the expensive initialization:

• Creates RPC client with connection pool
• Creates SWQOS clients (each with their own HTTP client)
• Initializes rent cache and starts background updater
