fix: Single source of truth for circuit names, and better circuit errors #390

aborgna-q · 2024-06-07T09:56:10Z

Stores the circuit name in the FuncDefn operations instead of a "name" metadata key.
In the future we will decode tket1 circuits into funtion definitions instead of Dfg blocks, but that currently causes errors due to Allow changing extension_reqs in SiblingSubgraph::create_simple_replacement. hugr#1175.
Circuit::circuit_signature returns a FunctionType instead of a PolyFuncType, since we (currently) don't allow parametric signatures.
Improves the errors when constructing and manipulating circuits.

This work is in the path to solving #385 and #389, but we will require some fixes in hugr (CQCL/hugr#1177) before fixing the support for non-Dfg rooted circuits.

Test coverage should improve once we merge #391.

Nice. Can we include Case?

tket2/src/circuit.rs

-        self.hugr.get_metadata(self.parent(), "name")?.as_str()
+        let op = self.hugr.get_optype(self.parent);
+        let name = match op {
+            OpType::FuncDecl(decl) => &decl.name,


A FuncDecl can never have a child.

+    let input_extensions = nodetype.input_extensions().cloned();
+    let mut optype = nodetype.into_op();
+    // Replace the parent node operation with the right operation type
+    // This must be able to process all implementers of `DataflowParent`.

+        OpType::FuncDefn(defn) => {
+            let mut sign: FunctionType = defn.signature.clone().try_into().map_err(|_| {


super nit, sig is a better name because sign is a word with an irrelevant meaning.

I think you do this so that it prints with the Display impl rather than Debug

Yes, it's a lot nicer to read the errors if we should the Display output when doing cargo test.

Followup to #390. Fixes #389. Closes #385. ~~Blocked by CQCL/hugr#1175 Fixes support for non-`Dfg` circuits and circuits with a non-root parent: Adds a `Circuit::extract_dfg(&self)` function that extracts the circuit into a new hugr with a DFG operation at the root. In some cases, like in a CFG DataflowBlock node, this requires some changes to the definition to eliminate the output sum type. Here I only implemented it for the kind of blocks produced by guppy. We could replace the manual implementation once CQCL/hugr#818 gets implemented. With this we can now fix #389 by extracting the circuit before using it as a replacement in `SimpleReplacement::create_simple_replacement`. Replaces `DfgBuilder` with `FunctionBuilder` where possible, so we can use named circuits in the tests. (This failed before due to the bug in CircuitRewrite).
