You async example is actually doing a blocking file write and requires you to load the whole image into memory before writing it to a file.

A better way to do that would be to have reqwest give you a byte stream and write to the file with Tokio's async IO library as shown in this stack overflow answer: https://stackoverflow.com/a/74283625
