1. Pumping Python modules using Rust PyCon Indonesia 2017 Vigneshwer Dhinakaran | Mozilla TechSpeaker | @dvigneshwer
2. What’s the Catch Whenever performance and control comes into the picture we are complacent that “ I can write a C extension ”
3. What’s the Catch Not many us write C extension in reality Writing C extension is scary & painful The community is awesome we already have such libraries cpython (C - 33% ) numpy (C - 53%) HeartBleed (OpenSSL bug)
4. What’s the main ask here for us? C’s Performance, Portability & Embeddability With Guaranteed Safety
5. Rust : Introduction System programming language that has great control like C/C++, delivers productivity like in Python, and is super safe
8. What does it offer? ➔ Strong safety guarantees ◆ No seg-faults ◆ No data-races ◆ Expressive type system ➔ Zero cost abstraction ◆ Without compromising on performance. ➔ Stability without stagnation ➔ Libraries & tools ecosystem Goal: Confident & productive systems programming
9. A bit complex example fn avg(list: &[f64]) -> f64 { let mut total = 0; for el in list{ total += *el; } total/list.len() as f64 }
10. HLL version fn avg(list: &[f64]) -> f64 { list.iter().sum::<f64>() / list.len() as f64 }
11. Parallel Version (Rayon) extern crate rayon; use rayon::prelude::*; fn avg(list: &[f64]) -> f64 { list.par_iter().sum::<f64>() / list.len() as f64 }
12. Demo Benchmarking fibonacci series
13. Benchmarking Results
14. where are we with Rust?
