⚠ eventcore breaking changes

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

Description:
A publicly-visible method 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/v0.45.0/src/lints/method_parameter_count_changed.ron

Failed in:
  eventcore::ProjectionRunner::new now takes 2 parameters instead of 3, in /tmp/.tmpemizEG/eventcore/eventcore/src/projection.rs:196

--- 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:
  eventcore::ProjectionRunner::with_checkpoint_store takes 1 generic types instead of 0, in /tmp/.tmpemizEG/eventcore/eventcore/src/projection.rs:222

--- 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/v0.45.0/src/lints/struct_missing.ron

Failed in:
  struct eventcore::LocalCoordinator, previously in file /tmp/.tmpdrFSjc/eventcore/src/projection.rs:221
  struct eventcore::CoordinatorGuard, previously in file /tmp/.tmpdrFSjc/eventcore/src/projection.rs:178
  struct eventcore::InMemoryCheckpointStore, previously in file /tmp/.tmpdrFSjc/eventcore/src/projection.rs:126

--- failure trait_requires_more_generic_type_params: trait now requires more generic type parameters ---

Description:
A trait now requires more generic type parameters than it used to. Uses of this trait that supplied the previously-required number of generic types will be broken. To fix this, consider supplying default values for newly-added generic types.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#trait-new-parameter-no-default
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.45.0/src/lints/trait_requires_more_generic_type_params.ron

Failed in:
  trait ProjectionRunner (3 -> 4 required generic types) in /tmp/.tmpemizEG/eventcore/eventcore/src/projection.rs:133

--- failure type_requires_more_generic_type_params: type now requires more generic type parameters ---

Description:
A type now requires more generic type parameters than it used to. Uses of this type that supplied the previously-required number of generic types will be broken. To fix this, consider supplying default values for newly-added generic types.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#trait-new-parameter-no-default
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.45.0/src/lints/type_requires_more_generic_type_params.ron

Failed in:
  Struct ProjectionRunner (3 -> 4 required generic types) in /tmp/.tmpemizEG/eventcore/eventcore/src/projection.rs:133

⚠ eventcore-testing breaking changes

--- failure declarative_macro_missing: macro_rules declaration removed or renamed ---

Description:
A `macro_rules!` declarative macro cannot be invoked by its prior name. The macro may have been renamed or removed entirely.
        ref: https://doc.rust-lang.org/reference/macros-by-example.html#path-based-scope
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.45.0/src/lints/declarative_macro_missing.ron

Failed in:
