Commit Message

Fix clippy lints, apply some pedantic fixes and general small improvements (#32)

* style(examples): directly have values as a type instead of casting

* style(examples/utils): ignore unused warnings

* style: run clippy auto fix

and remove redundant tests from "label"

* style: apply some clippy pedantic auto fixes

* test: set specific strings for "should_panic"

So that other panics are catched as failed tests.

* style(bar_chart): remove casting to "u64" when "usize" is directly provided and needed

* refactor(table): move making rows to own function

To appease "clippy::too_many_lines" and slightly reduce nesting.

* style: add "#[must_use]" where applicable

To hint not to forget a value.
