⚠ sideway breaking changes

--- failure method_requires_different_generic_type_params: method now requires a different number of generic type parameters ---

Description:
A method now requires a different number of generic type parameters than it used to. Uses of this method that supplied the previous number of generic types will be broken.
        ref: https://doc.rust-lang.org/reference/items/generics.html
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.45.0/src/lints/method_requires_different_generic_type_params.ron

Failed in:
  sideway::ibverbs::queue_pair::QueuePairBuilder::setup_send_cq takes 1 generic types instead of 0, in /tmp/.tmp43aRIK/sideway/src/ibverbs/queue_pair.rs:819
  sideway::ibverbs::queue_pair::QueuePairBuilder::setup_recv_cq takes 1 generic types instead of 0, in /tmp/.tmp43aRIK/sideway/src/ibverbs/queue_pair.rs:836

--- failure type_mismatched_generic_lifetimes: type now takes a different number of generic lifetimes ---

Description:
A type now takes a different number of generic lifetime parameters. Uses of this type that name the previous number of parameters will be broken.
