  • Don't use .ok() before unwrapping via .expect() on a Result.
  • Use .map() to modify data inside Options instead of using .and_then(|x| Some(y))
  • Use .as_deref() instead of .as_ref().map(Deref::deref)
  • Don't use "if let" bindings to only check a value and not actually bind anything.
  • Use single-char patter on {ends,starts}_with and remove clone on copy type.

For example:  `if let Some(_) = foo() {}`	can be reduced to	`if foo().is_some() {}`   (clippy::redundant_pattern_matching)

These were introduced since I last fixed most of these occurences. (clippy::clone_on_copy, clippy::single_char_pattern)
