feat!: Type-safe access for node metadata by aborgna-q · Pull Request #2755 · Quantinuum/hugr

aborgna-q · 2025-12-12T10:22:08Z

Closes #2753
Closes #2651

Adds a Metadata trait that can be used for type-safe access of metadata entries on the rust library.
Moves the existing metadata keys definitions to crate::metadata.

To access a metadata value, the new methods take the metadata marker as a type parameter,

struct SomeUsizeMetadata;
impl Metadata for SomeUsizeMetadata {
    type Type<'hugr> = usize;
    const KEY: &'static str = "some.key";
}

fn HugrView::get_metadata<M: Metadata>(&self, node: Self::Node) -> Option<<M as Metadata>::Type<'_>>;

hugr.set_metadata::<SomeUsizeMetadata>(node, 42);
let val: Some(usize) = hugr.get_metadata::<SomeUsizeMetadata>(node);

Note that we always need to explicitly set the metadata marker when calling get_metadata, since the marker cannot be derived from the return type.

An alternative design would have been to return the Metadata object itself,

fn HugrView::get_metadata<M: Metadata>(&self, node: Self::Node) -> Option<Metadata<'_>>;

but in most cases we are just storing intrinsic types for payloads, so wrapping them into new structs is just extra boilerplate. We are already getting the type safety from explicitly stating the markers on the method calls.

BREAKING CHANGE: get/set_metadata methods now use the new Metadata trait. Use get_metadata_any for untyped access.

The metadata trait design looks good to me, but I can't say much about the rust code.

maximilianruesch

Probably worth having a look which of the keys listed in #2431 really exist in HUGR code (or where they exist) and making sure they are captured by this PR (as this PR also closes the centralisation issue).

aborgna-q · 2025-12-15T11:47:39Z

Probably worth having a look which of the keys listed in #2431

Good catch! It looks like the entries we're missing from there are all from the hugr-model encoding.
Those encoding keys do not mix with the metadata entries used in the Hugr representation (anything from Hugr gets wrapped in a compat.meta_jsonentry).

I think adding them here would only make for confusion.
If we merge the model and the Hugr metadata at some point then we can decide whether to re-export those in hugr-core.

Not sure the generator deserialization change is in scope

is this more useful than the existing json encoding?

Fair. I reverted back the changes and left serde_json::Value as the metadata value.
I'll add the change in another PR

Replaces the `serde_json::Value` metadata payload for the generator description added in #2755 with a proper `GeneratorDesc` type. This moves the logic for decoding either json strings or json dicts with `name`/`version` fields from `format_generator` into a Deserialize implementation. BREAKING CHANGE: Removed `hugr::envelope::format_generator`. The `HugrGenerator` metadata returns an already-parsed object that implements `Display`.

@guppy

…ding emulators (#1378) Added a keyword argument to `@guppy` decorator for annotation of maximum qubits required for the function, which allows the emulator to be built without specifying a number of qubits (if given on the entrypoint function): ```python @guppy(max_qubits=1) def main() -> None: result("c", measure(qubit())) main.emulator().run() ``` The feature (still) complains if you: - pass no qubit count anywhere - pass a qubit count to the emulator that is insufficient to cover the qubit count hinted on the entrypoint The emulation will still crash if you do sufficient hinting, but the allocated number of qubits is too low for the number of required qubits. Additionally (or perhaps more importantly for future developments), this PR adds a notion of metadata to the Guppy compiler which gets passed onto the HUGR. This metadata is currently only attached to function definitions, but could be extended to live on all definitions (and thus be able to be attached to all HUGR nodes that are created from Guppy). For a full list of TODOs, see below. BREAKING CHANGE: - The first argument to `add_unitarity_metadata` is now named `node` instead of `func`, since its type was raised to allow for more HUGR nodes to be fed. Migration is trivial. > [!NOTE] > This PR is only "breaking" `guppylang-internals`, and not `guppylang` Before this PR is merged (or relatively soon thereafter), the following things must/should/will happen: - HUGR adds type-safe metadata access and refactors its core keys: Quantinuum/hugr#2755 - HUGR exports type-safe access and core keys to Python bindings: Quantinuum/hugr#2757 - Guppy uses the new core keys internally - TKET uses the new pattern to define a unitary key (e.g.`tket.modify.unitarity`, replacing the [string literal](https://github.com/Quantinuum/tket2/blob/2918a67c6c5ce688ccd184192284355205047091/tket/src/modifier.rs#L66)) and defines a new `max_qubits` key (e.g. `tket.hint.max_qubits`), exporting both to Python bindings - Guppy adds TKET as a direct dependency - Guppy uses the new keys internally to replace `"unitary"` as well as the existing string literal for MaxQubits - Guppy adds the ability to propagate metadata to any HUGR node, attaching it to any def (?) Closes #1297

This release includes various breaking refactors and improvements: - A lot of work has been done towards linking Hugrs. Now module-rooted Hugrs can be linked together using configurable policies. - `ValueArray` has been removed. - A type-safe API for accessing metadata on nodes has been added. - Envelopes now have an extensive API for progressively describing a package, and failing gracefully on errors. - The MSRV has been bumped to Rust 1.89, and the public pyo3 dependency has been updated to 0.27. - Multiple deprecated definitions have been removed. ---- ## 🤖 New release * `hugr-model`: 0.24.3 -> 0.25.0 (✓ API compatible changes) * `hugr-core`: 0.24.3 -> 0.25.0 (⚠ API breaking changes) * `hugr-llvm`: 0.24.3 -> 0.25.0 (✓ API compatible changes) * `hugr-passes`: 0.24.3 -> 0.25.0 (⚠ API breaking changes) * `hugr-persistent`: 0.3.4 -> 0.4.0 (✓ API compatible changes) * `hugr`: 0.24.3 -> 0.25.0 (✓ API compatible changes) * `hugr-cli`: 0.24.3 -> 0.25.0 (⚠ API breaking changes) ### ⚠ `hugr-core` breaking changes ```text --- failure enum_marked_non_exhaustive: enum marked #[non_exhaustive] --- Description: A public enum has been marked #[non_exhaustive].
