Loudest Cargo 😱 How to setup Clippy to be as verbose as possible.

loud_cargo.toml

# Canonical lints for whole crate
#
# Official docs:
#   https://doc.rust-lang.org/nightly/clippy/lints.html
# Useful app to lookup full details of individual lints:
#   https://rust-lang.github.io/rust-clippy/master/index.html
# 
# We set base lints to give the fullest, most pedantic feedback possible.
# Though we prefer that they are just warnings during development so that build-denial
# is only enforced in CI.

# `clippy::all` is already on by default. It implies the following:
#   * clippy::correctness code that is outright wrong or useless
#   * clippy::suspicious code that is most likely wrong or useless
#   * clippy::complexity code that does something simple but in a complex way
#   * clippy::perf code that can be written to run faster
#   * clippy::style code that should be written in a more idiomatic way
