This paper presents a benchmarking analysis comparing the performance of data structures implemented in PyO3 Rust plugins against native Python implementations. The benchmarked data structures include Structure of Arrays (SoA), Array of Structures (AoS), linked lists, and vectors. Rust and Python implementations of each structure were compared, facilitated by PyO3’s wrapping functionality. Benchmarks assessed data access and manipulation, running for 100 iterations across varying element sizes. Results revealed the Rust data structures outperformed the native python implementations with the exception of the Rust AoS plugin.

摘要

This paper presents a benchmarking analysis comparing the performance of data structures implemented in PyO3 Rust plugins against native Python implementations. The benchmarked data structures include Structure of Arrays (SoA), Array of Structures (AoS), linked lists, and vectors. Rust and Python implementations of each structure were compared, facilitated by PyO3’s wrapping functionality. Benchmarks assessed data access and manipulation, running for 100 iterations across varying element sizes. Results revealed the Rust data structures outperformed the native python implementations with the exception of the Rust AoS plugin.
