⚠ salsa 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/v0.40.0/src/lints/auto_trait_impl_removed.ron

Failed in:
  type IngredientImpl is no longer UnwindSafe, in /tmp/.tmp6FxNmg/salsa/src/function.rs:96

--- failure enum_variant_added: enum variant added on exhaustive enum ---

Description:
A publicly-visible enum without #[non_exhaustive] has a new variant.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#enum-variant-new
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.40.0/src/lints/enum_variant_added.ron

Failed in:
  variant EventKind:DidInternValue in /tmp/.tmp6FxNmg/salsa/src/event.rs:96
  variant EventKind:DidReinternValue in /tmp/.tmp6FxNmg/salsa/src/event.rs:105
  variant CycleRecoveryStrategy:Fixpoint in /tmp/.tmp6FxNmg/salsa/src/cycle.rs:83

--- failure enum_variant_missing: pub enum variant removed or renamed ---

Description:
A publicly-visible enum has at least one variant that 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/v0.40.0/src/lints/enum_variant_missing.ron

Failed in:
  variant CycleRecoveryStrategy::Fallback, previously in file /tmp/.tmpYqyGYj/salsa/src/cycle.rs:108

--- failure function_missing: pub fn removed or renamed ---

Description:
A publicly-visible function cannot be imported by its prior path. A `pub use` may have been removed, or the function 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/v0.40.0/src/lints/function_missing.ron

Failed in:
  function salsa::plumbing::should_backdate_value, previously in file /tmp/.tmpYqyGYj/salsa/src/function.rs:135

--- 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/v0.40.0/src/lints/function_requires_different_generic_type_params.ron

Failed in:
  function par_map (4 -> 5 generic types) in /tmp/.tmp6FxNmg/salsa/src/parallel.rs:5

--- failure struct_missing: pub struct removed or renamed ---

Description:
A publicly-visible struct cannot be imported by its prior path. A `pub use` may have been removed, or the struct 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/v0.40.0/src/lints/struct_missing.ron

Failed in:
  struct salsa::plumbing::Cycle, previously in file /tmp/.tmpYqyGYj/salsa/src/cycle.rs:20
  struct salsa::Cycle, previously in file /tmp/.tmpYqyGYj/salsa/src/cycle.rs:20

--- failure trait_method_added: pub trait method added ---

Description:
A non-sealed public trait added a new method without a default implementation, which breaks downstream implementations of the trait
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#trait-new-item-no-default
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.40.0/src/lints/trait_method_added.ron

Failed in:
  trait method salsa::plumbing::function::Configuration::values_equal in file /tmp/.tmp6FxNmg/salsa/src/function.rs:59
  trait method salsa::plumbing::function::Configuration::cycle_initial in file /tmp/.tmp6FxNmg/salsa/src/function.rs:72

--- failure trait_method_missing: pub trait method removed or renamed ---

Description:
A trait method is no longer callable, and may have been renamed or removed entirely.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#major-any-change-to-trait-item-signatures
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.40.0/src/lints/trait_method_missing.ron

Failed in:
  method should_backdate_value of trait Configuration, previously in file /tmp/.tmpYqyGYj/salsa/src/function.rs:60

--- failure trait_method_parameter_count_changed: pub trait method parameter count changed ---

Description:
A trait method now takes a different number of parameters.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#major-any-change-to-trait-item-signatures
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.40.0/src/lints/trait_method_parameter_count_changed.ron

Failed in:
  Ingredient::remove_stale_output now takes 5 instead of 4 parameters, in file /tmp/.tmp6FxNmg/salsa/src/ingredient.rs:96
  Configuration::recover_from_cycle now takes 4 instead of 3 parameters, in file /tmp/.tmp6FxNmg/salsa/src/function.rs:77
