The Zero-Latency Imperative

In algorithmic finance and high-frequency trading (HFT), milliseconds are an eternity. Market orders must execute in single-digit microseconds. For decades, C and C++ held an uncontested monopoly over this domain.

However, in 2026, Rust has emerged as the premier choice for new trading engines, exchange matching gateways, and high-throughput networking stacks.
