### ⚠️ `hugr-model` 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/v0.37.0/src/lints/constructible_struct_adds_field.ron

--- failure enum_missing: pub enum removed or renamed ---

Description:
A publicly-visible enum cannot be imported by its prior path. A `pub use` may have been removed, or the enum itself may have been renamed or removed entirely.

Description:
An enum's exhaustive struct variant has a new field, which has to be included when constructing or matching on this variant.
        ref: https://doc.rust-lang.org/reference/attributes/type_system.html#the-non_exhaustive-attribute
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.37.0/src/lints/enum_struct_variant_field_added.ron

--- 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/v0.37.0/src/lints/enum_struct_variant_field_missing.ron

--- 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/v0.37.0/src/lints/enum_variant_added.ron

--- 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/v0.37.0/src/lints/enum_variant_missing.ron

--- failure struct_repr_transparent_removed: struct repr(transparent) removed ---

Description:
repr(transparent) was removed from a struct whose layout was part of the public ABI. This can cause its memory layout to change, breaking FFI use cases.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#repr-transparent-remove
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.37.0/src/lints/struct_repr_transparent_removed.ron
