⚠ timely_communication breaking changes

--- failure auto_trait_impl_removed: auto trait no longer implemented ---

Description:
A public type has stopped implementing one or more auto traits. This can break downstream code that depends on the traits being implemented.
        ref: https://doc.rust-lang.org/reference/special-types-and-traits.html#auto-traits
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.46.0/src/lints/auto_trait_impl_removed.ron

Failed in:
  type MergeQueue is no longer Sync, in /tmp/.tmpyInCzT/timely-dataflow/communication/src/allocator/zero_copy/bytes_exchange.rs:33
  type MergeQueue is no longer UnwindSafe, in /tmp/.tmpyInCzT/timely-dataflow/communication/src/allocator/zero_copy/bytes_exchange.rs:33
  type MergeQueue is no longer RefUnwindSafe, in /tmp/.tmpyInCzT/timely-dataflow/communication/src/allocator/zero_copy/bytes_exchange.rs:33

--- failure derive_trait_impl_removed: built-in derived trait no longer implemented ---

Description:
A public type has stopped deriving one or more traits. This can break downstream code that depends on those types implementing those traits.
        ref: https://doc.rust-lang.org/reference/attributes/derive.html#derive
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.46.0/src/lints/derive_trait_impl_removed.ron

Failed in:
  type MergeQueue no longer derives Clone, in /tmp/.tmpyInCzT/timely-dataflow/communication/src/allocator/zero_copy/bytes_exchange.rs:33

--- failure enum_struct_variant_field_missing: pub enum struct variant's field removed or renamed ---

Description:
A publicly-visible enum has a struct variant whose field is no longer available under its prior name. It may have been renamed or removed entirely.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#item-remove
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.46.0/src/lints/enum_struct_variant_field_missing.ron

Failed in:
  field log_fn of variant Config::Cluster, previously in file /tmp/.tmpW2k07I/timely_communication/src/initialize.rs:42
  field log_fn of variant Config::Cluster, previously in file /tmp/.tmpW2k07I/timely_communication/src/initialize.rs:42

--- failure function_parameter_count_changed: pub fn parameter count changed ---

Description:
A publicly-visible function now takes a different number of parameters.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#fn-change-arity
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.46.0/src/lints/function_parameter_count_changed.ron

Failed in:
  timely_communication::allocator::zero_copy::initialize::initialize_networking_from_sockets now takes 5 parameters instead of 6, in /tmp/.tmpyInCzT/timely-dataflow/communication/src/allocator/zero_copy/initialize.rs:62
  timely_communication::allocator::zero_copy::initialize::initialize_networking now takes 6 parameters instead of 7, in /tmp/.tmpyInCzT/timely-dataflow/communication/src/allocator/zero_copy/initialize.rs:41
  timely_communication::allocator::zero_copy::tcp::send_loop now takes 6 parameters instead of 5, in /tmp/.tmpyInCzT/timely-dataflow/communication/src/allocator/zero_copy/tcp.rs:137

--- failure method_parameter_count_changed: pub method parameter count changed ---

Description:
A publicly-visible method now takes a different number of parameters, not counting the receiver (self) parameter.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#fn-change-arity
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.46.0/src/lints/method_parameter_count_changed.ron

Failed in:
  timely_communication::allocator::ProcessBuilder::new_typed_vector now takes 3 parameters instead of 2, in /tmp/.tmpyInCzT/timely-dataflow/communication/src/allocator/mod.rs:155
  timely_communication::allocator::ProcessBuilder::new_bytes_vector now takes 3 parameters instead of 2, in /tmp/.tmpyInCzT/timely-dataflow/communication/src/allocator/mod.rs:163
