Hello, Thank you it is working. I created a writing and reading benchmark. In both cases Python is about 3 times faster than Rust.
Please find below the results and attached the codes (create_csv.py/rs has to run first, because it creates a csv file which is used for csv.py/rs) *BENCHMARK 1*: Writting 4000000 lines to a file $ time python csv_create.py real 0m3.620s user 0m1.942s sys 0m0.339s $ ls -ahl csv.csv -rw-r--r-- 1 mictadlo mictadlo 226M Apr 9 09:05 csv.csv $ time ./csv_create real 0m11.299s user 0m3.222s sys 0m5.973s $ ls -ahl csv.csv -rw-r--r-- 1 mictadlo mictadlo 226M Apr 9 09:07 csv.csv *BENCHMARK 2: *Readind a csv file and trim each field $ time python csv.py real 0m22.136s user 0m21.728s sys 0m0.095s $ time ./csv real 1m6.796s user 1m6.364s sys 0m0.145s If you guys happy benchmark than I could commit it to git. What is the git command to commit in 'src/test/bench'? Thank you in advance.
