pad short lines when reading from non-file io

[kleinhenz]

Makes the behavior match between reading from io.StringIO and reading from a file.

Hi, thanks for the contribution. In general I think this is a good idea. Let's wait for the CI to see the performance impact on this. As alternative we could also justify the line on the Rust side, if the impact is measurable.

I had originally put this in the constructor on the rust side but then I didn't want to make it happen twice in the more common read path. I didn't measure the performance though so maybe it doesn't really make a big difference.

Now I understand what you mean, I forgot that these lines existed.

fastpdb/src/lib.rs

Lines 76 to 78 in 64d6b14

	let lines = contents.lines().map(
	|line| format!("{:<80}", line)
	).collect();

In this case this seems like a sensible solution to me, thanks 👍
