Way to specify file extension of temporary file about edit HOT 4 CLOSED

It would be pretty easy to copy what edit_bytes is doing but with your own NamedTempFile, something like this:

let mut file = Builder::new()
    .suffix(".toml")
    .tempfile()?;
file.write(buf.as_ref())?;

let path = file.into_temp_path();
edit_file(&path)?;

let edited = fs::read(&path)?;

path.close()?;

It's slightly more annoying if you also want to convert to a UTF-8 string.

I'd be open to adding a function for this specific use case, like edit but taking a NamedTempFile as an argument; then the user can specify the directory, prefix, suffix, etc. with a tempfile::Builder.

On another note, if you're parsing TOML files (or any format supported by serde, in principle) with edit, I've written some code for validation with serde (both syntax-wise and for a specific config) and user-friendly in-editor syntax errors for another project of mine that could definitely be reused. (run storm config for a demo). I'm looking into refactoring this into its own crate (edit_toml?) but I haven't gotten around to it yet (and the implementation for storm isn't 100% complete).

I like to have this too :)

Implement the feature. Please give feedback :)
