Use Self where possible

[pintariching]

Is there any benefit to using Self instead of the struct name? Or is it just a matter of convention?

Also the same question for vec![] vs Vec::new().

It's more idiomatic. Also you already use Self:: instead of the struct name in several places so this unifies it.

The changes seem to make the build fail. Can you check it out?

[adamnemecek]

Done.
