openigtlink-rust 0.2.0

//! Serialization benchmarks
//!
//! Measures message serialization performance (encoding without network I/O).
//!
//! Note: Originally network benchmarks, but network I/O is unsuitable for
//! Criterion's tight iteration loops due to port allocation overhead.
//! Use examples/performance_test.rs for real network performance testing.
