# All disabled checks have to come with an explanatory comment that states why they were disabled!
#
# modernize-use-trailing-return-type:
#  Purely stylistic, makes function signature longer
#
# readability-identifier-length:
#  Things like std::ostream os; nlohmann::json j; are popular. Reviewer can decide on those cases
#
# readability-implicit-bool-conversion:
#  Makes packet-parsing (bool field that occupies a byte or bitfield) annoying
#
# hicpp-special-member-functions:
#  Alias for cppcoreguidelines-special-member-functions, which is enabled. If both are enabled,
#  the CheckOptions below have to be specified twice.
