Rust download file

If it works out, we log the file name and return a success message to the caller. It works! And all that in less than a hundred lines of Rust code with some very basic error handling and input validation using just a couple of crates.

You can find the full example code at GitHub. Efficiently and robustly handling file uploads in a web service is not an easy task, but the Rust ecosystem provides all the tools to do so, even with options to asynchronously stream files for additional speed and flexibility. The above example is a starting point for a real-world implementation.

That said, the fundamentals are already there in the Rust web ecosystem to create great upload and download experiences for your users. Instead of guessing why problems happen, you can aggregate and report on what state your application was in when an issue occurred.

Thanks for the interesting tutorial. I expanded it slightly by adding cors. This works fine for the download path, but it seems that its not working even though compiling for the upload part.
