⚠ cot_codegen breaking changes

--- failure enum_no_repr_variant_discriminant_changed: enum variant had its discriminant change value ---

Description:
The enum's variant had its discriminant value change. This breaks downstream code that used its value via a numeric cast like `as isize`.
        ref: https://doc.rust-lang.org/reference/items/enumerations.html#assigning-discriminant-values
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.51.0/src/lints/enum_no_repr_variant_discriminant_changed.ron

Failed in:
  variant VisibleSymbolKind::Const 2 -> 4 in /tmp/.tmpw0Q7xA/cot/cot-codegen/src/symbol_resolver.rs:197

--- 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/v0.51.0/src/lints/enum_variant_added.ron

Failed in:
  variant VisibleSymbolKind:Enum in /tmp/.tmpw0Q7xA/cot/cot-codegen/src/symbol_resolver.rs:195
  variant VisibleSymbolKind:TypeAlias in /tmp/.tmpw0Q7xA/cot/cot-codegen/src/symbol_resolver.rs:196

--- warning partial_ord_enum_variants_reordered: enum variants reordered in #[derive(PartialOrd)] enum ---

Description:
A public enum that derives PartialOrd had its variants reordered. #[derive(PartialOrd)] uses the enum variant order to set the enum's ordering behavior, so this change may break downstream code that relies on the previous order.
        ref: https://doc.rust-lang.org/std/cmp/trait.PartialOrd.html#derivable
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.51.0/src/lints/partial_ord_enum_variants_reordered.ron

Failed in:
  VisibleSymbolKind::Const moved from position 3 to 5, in /tmp/.tmpw0Q7xA/cot/cot-codegen/src/symbol_resolver.rs:197

⚠ cot 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/v0.51.0/src/lints/auto_trait_impl_removed.ron

Failed in:
  type MigrationEngineError is no longer UnwindSafe, in /tmp/.tmpw0Q7xA/cot/cot/src/db/migrations.rs:47
  type MigrationEngineError is no longer RefUnwindSafe, in /tmp/.tmpw0Q7xA/cot/cot/src/db/migrations.rs:47

--- 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/v0.51.0/src/lints/derive_trait_impl_removed.ron

Failed in:
  type MigrationEngineError no longer derives Clone, in /tmp/.tmpw0Q7xA/cot/cot/src/db/migrations.rs:47

--- 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/v0.51.0/src/lints/method_parameter_count_changed.ron

Failed in:
  cot::db::query::Expr::as_sea_query_expr takes 0 parameters in /tmp/.tmphJglTh/cot/src/db/query.rs:1007, but now takes 1 parameters in /tmp/.tmpw0Q7xA/cot/cot/src/db/query/expr.rs:1314

--- 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/v0.51.0/src/lints/method_requires_different_generic_type_params.ron

Failed in:
  cot::db::query::Query::count takes 1 generic types instead of 0, in /tmp/.tmpw0Q7xA/cot/cot/src/db/query.rs:247

--- 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/v0.51.0/src/lints/struct_missing.ron

Failed in:
  struct cot::db::query::FieldRef, previously in file /tmp/.tmphJglTh/cot/src/db/query.rs:1033

--- 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/v0.51.0/src/lints/trait_method_added.ron

Failed in:
  trait method cot::db::DatabaseBackend::count in file /tmp/.tmpw0Q7xA/cot/cot/src/db.rs:3346

--- failure trait_method_receiver_ref_became_mut: trait method receiver changed from immutable to mutable reference ---

Description:
A trait method's receiver changed from an immutable reference to a mutable one.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#trait-item-signature
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.51.0/src/lints/trait_method_receiver_ref_became_mut.ron

--- 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

⚠ cot-cli breaking changes

--- failure constructible_struct_adds_field: struct exhaustively constructible through public API adds field ---

Description:
A pub struct that could be exhaustively constructed with a literal using only public API has a new pub field, breaking existing exhaustive literals.
        ref: https://doc.rust-lang.org/reference/expressions/struct-expr.html
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.51.0/src/lints/constructible_struct_adds_field.ron

Failed in:

       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.51.0/src/lints/constructible_struct_adds_private_field.ron
