Dependency

This draft follows #9563, now rebased onto its published strict-default common binder head 832f9bb454. Merge the common change first.

GitHub cannot use a fork-only branch as the base branch of an upstream PR, so the base is main. Until #9563 lands, the comparison includes its common commits. The queue-only change is 999d1f3f82.

Summary

Replace the queue-local clinic_args adapter and manual ArgSpec parsing with four ordinary FromArgs structs.
Remove temporary argument buffers, cells, and object clones introduced only for binding.
Keep raw objects through numeric conversion and queue operations, preserve conversion order and queue-specific diagnostics, and distinguish omitted values from explicit None.
Keep registration downcasts consuming their fields instead of cloning them.

The queue-only implementation is unchanged by this rebase: one file, +80/-107. The stack now includes #9563's strict defaults, dispatch overrides, custom-parser composition fix, and SQLite marker cleanup.

Validation

Fresh runtime validation of this rebased queue head is pending. The common parent has passed a SQLite-enabled release build, strict all-target workspace Clippy, and 19 regression modules (4,577 tests run, 455 skipped); its C-API and workspace aggregates continue after publication.

Before the rebase, the unchanged queue implementation passed its focused probe on both RustPython and CPython 3.15.0: 11 signatures, 25 invalid-call checks, conversion order, and queue round trips. Its release build and strict workspace Clippy also passed.

The full interpreter queue suite was skipped because it requires a GIL-disabled runtime; that invocation executed zero tests. This draft is not a claim of a complete fresh green run.

Summary by CodeRabbit

Refactor
- Updated queue argument handling while preserving existing queue operations, return values, and type checks.

Walkthrough

Queue-module functions now use FromArgs-derived structs instead of manual ArgSpec parsing. Optional integer arguments retain a missing-value default of -1. Queue operations, result shapes, and type checks remain unchanged.

Changes: Queue Argument Parsing

Layer / File(s)	Summary
Queue argument structures `crates/vm/src/stdlib/_interpqueues.rs`	Adds derived argument structs and an optional integer conversion helper for queue function inputs.
Queue handler migration `crates/vm/src/stdlib/_interpqueues.rs`	Updates queue creation, item insertion, queue ID operations, and heap-type registration to use parsed struct fields. Existing queue defaults, operations, error mapping, and validations remain in place.

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Refactor

Merge Risk: Minimal · up to 00878

No concrete blocking issue is established for the queue argument-binding migration. Merge readiness remains subject to normal checks; fresh runtime validation is still pending.

Full details: Title check

Explanation

The title "Bind interpreter queues with FromArgs" matches the main change. The raw summary says queue-module argument parsing moves from ArgSpec/FuncArgs and the qid_arg helper to FromArgs-derived argument structs, and the objectives say the same. The title is specific and concise. It names the queue module and the FromArgs mechanism, so a teammate scanning history can tell what changed.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 12 functions across 1 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Test compile-time rejection through ordinary binding.

Add a compile-fail test that instantiates an ordinary binding with malformed metadata, such as (PosArgs, i32). The current test calls BindingShape::validated directly, so it would still pass if check_before_convert stopped rejecting that composition.
