This PR contains breaking changes to the public Rust API.

cargo-semver-checks summary

--- 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/v0.39.0/src/lints/auto_trait_impl_removed.ron

Failed in:
type NonLocalEdgesError is no longer UnwindSafe, in /home/runner/work/hugr/hugr/PR_BRANCH/hugr-passes/src/non_local.rs:70
type NonLocalEdgesError is no longer RefUnwindSafe, in /home/runner/work/hugr/hugr/PR_BRANCH/hugr-passes/src/non_local.rs:70

--- 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/v0.39.0/src/lints/derive_trait_impl_removed.ron

Failed in:
type NonLocalEdgesError no longer derives Clone, in /home/runner/work/hugr/hugr/PR_BRANCH/hugr-passes/src/non_local.rs:70
type NonLocalEdgesError no longer derives Eq, in /home/runner/work/hugr/hugr/PR_BRANCH/hugr-passes/src/non_local.rs:70

--- failure enum_marked_non_exhaustive: enum marked #[non_exhaustive] ---

Description:
A public enum has been marked #[non_exhaustive]. Pattern-matching on it outside of its crate must now include a wildcard pattern like `_`, or it will fail to compile.
      ref: https://doc.rust-lang.org/cargo/reference/semver.html#attr-adding-non-exhaustive
     impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.39.0/src/lints/enum_marked_non_exhaustive.ron

Failed in:
enum NonLocalEdgesError in /home/runner/work/hugr/hugr/PR_BRANCH/hugr-passes/src/non_local.rs:70
