How do I get a file as a String/&str?

[beyarkay]

I want to get https://github.com/beyarkay/eskom-calendar/blob/main/manually_specified.yaml as a String or &str so that I can parse the YAML and edit it. How do I do this? I've tried:

let body = octocrab::instance()
    .repos("beyarkay", "eskom-calendar")
    .raw_file("main".to_string(), "manually_specified.yaml")
    .await
    .unwrap()
    .into_body();

And that gets me a hyper::Body object, but I can't figure out how to extract the content from it. I've tried to look online, but all the answers 1 2 3 4 suggest things that don't work with the latest version of hyper.

Is it possible to get the raw text of a file hosted on github? I've resorted to using reqwest and just downloading the raw.githubusercontent.com version of the file, but the raw_file method sounds like it should be able to give me the raw file.
