- Build the release version of code using
foo@bar:~$ cargo build -r- This will generate a binary target/release/json_parser
- Use the binary the following way to process the json file
foo@bar:~$ target/release/json_parser <INPUT_FILE_PATH> <OUTPUT_FILE_PATH>- This will generate the processed json file at the <OUTPUT_FILE_PATH>.
I have timed this code using two tools
- time: The time command runs the specified program command with the given arguments. When command finishes, time writes a message to standard error giving timing statistics about this program run.
- hyperfine: A command line based benchmarking tool
Because of the file sizes it is impossible to compare each line manually, I used three command line tools to validate the result.
- grep: grep is used to search the file for occurances of the query string. We can see 4 lines in the input file where ';' is present and 0 in the output file.
- wc: wc is a tool used to check the number of lines in a file. Here we can see both input and output have same number of lines.
- diff: diff is a command line tool to compare files.
