⚠ differential-dataflow breaking changes

--- failure constructible_struct_adds_field: externally-constructible struct adds field ---

Description:
A pub struct constructible with a struct literal has a new pub field. Existing struct literals must be updated to include the new field.
        ref: https://doc.rust-lang.org/reference/expressions/struct-expr.html
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.43.0/src/lints/constructible_struct_adds_field.ron

Failed in:
  field OrdKeyBatch.value in /tmp/.tmpoocbgX/differential-dataflow/differential-dataflow/src/trace/implementations/ord_neu.rs:797
  field OrdKeyBatch.value in /tmp/.tmpoocbgX/differential-dataflow/differential-dataflow/src/trace/implementations/ord_neu.rs:797

--- failure function_requires_different_generic_type_params: function now requires a different number of generic type parameters ---

Description:
A function now requires a different number of generic type parameters than it used to. Uses of this function that supplied the previous number of generic types (e.g. via turbofish syntax) will be broken.
        ref: https://doc.rust-lang.org/reference/items/generics.html
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.43.0/src/lints/function_requires_different_generic_type_params.ron

Failed in:
  function concatenate (5 -> 3 generic types) in /tmp/.tmpoocbgX/differential-dataflow/differential-dataflow/src/collection.rs:726

--- failure module_missing: pub module removed or renamed ---

Description:
A publicly-visible module cannot be imported by its prior path. A `pub use` may have been removed, or the module may have been renamed, removed, or made non-public.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#item-remove
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.43.0/src/lints/module_missing.ron

Failed in:
  mod differential_dataflow::operators::negate, previously in file /tmp/.tmpoaBel7/differential-dataflow/src/operators/negate.rs:1

--- failure trait_allows_fewer_generic_type_params: trait now allows fewer generic type parameters ---

Description:
A trait now allows fewer generic type parameters than it used to. Uses of this trait that supplied all previously-supported generic types will be broken.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#trait-new-parameter-no-default
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.43.0/src/lints/trait_allows_fewer_generic_type_params.ron

  trait AsCollection allows 4 -> 2 generic types in /tmp/.tmpoocbgX/differential-dataflow/differential-dataflow/src/collection.rs:690

--- failure trait_missing: pub trait removed or renamed ---

Description:
A publicly-visible trait cannot be imported by its prior path. A `pub use` may have been removed, or the trait itself 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/v0.43.0/src/lints/trait_missing.ron

--- failure trait_newly_sealed: pub trait became sealed ---

Description:
A publicly-visible trait became sealed, so downstream crates are no longer able to implement it
        ref: https://rust-lang.github.io/api-guidelines/future-proofing.html#sealed-traits-protect-against-downstream-implementations-c-sealed
