## Summary / motivation (required)
When running ci, instead of manually compiling cargo-llvm-cov and
cargo-nextest when not cached, this pr pulls them in as prebuilt
binaries instead
## Steps to reproduce (required, use N/A if not applicable)
N/A
## How to test (required)
CI should pass, and running `./check` and `just test --coverage` should
work locally too
### Checklist (minimum)
- [x] I ran `./ninja check` or an equivalent relevant check locally.
- [ ] I added or updated tests when the change is non-trivial or
behavior changed.
### Details
Continuing from
https://github.com/ankitects/anki/issues/5134#issuecomment-4936603431,
we can avoid installing the crates globally when run locally, but in ci
it doesn't really matter so we can use install-action as per normal.
W.r.t nextest's features, all `default-no-update` does is remove its
ability to self-update. Since we're puling in prebuilt binaries during
ci there's no difference
I've left out n2 for now, as without a release workflow on its repo or
on anki's fork, we'd still have to compile it ourselves (caching it can
be unsafe, but it sort of is already cached by setup-rust-toolchain?)
## Scope
- [x] This PR is focused on one change (no unrelated edits).
## Linked issue
Closes#4925
## Summary / motivation
Adds a comprehensive unit test suite for
`rslib/src/notetype/service.rs`, which previously had zero tests. The
file implements the `NotetypesService` gRPC trait for `Collection` — 20
service methods and 6 `From` trait conversions used by both the Qt
frontend (via the legacy JSON adapter path) and the modern proto path.
Tests are organized into five commits by concern:
- **From trait conversions** (`NotetypeId` round-trip,
`ChangeNotetypeRequest ↔ ChangeNotetypeInput` mappings including the `-1
→ None` sentinel and `is_cloze` flag)
- **Legacy JSON adapters** (`add_notetype_legacy`,
`update_notetype_legacy`, `get_notetype_legacy`,
`get_stock_notetype_legacy` for all 6 stock kinds, and all 3 branches of
`add_or_update_notetype`)
- **CRUD service methods** (add, get, update, remove — happy paths,
error paths, and side effects such as card generation when a template is
added)
- **Auxiliary methods** (`get_notetype_names_and_counts`,
`get_aux_notetype_config_key`, `get_aux_template_config_key` including
the Cloze branch and the error path for unknown IDs)
- **Coverage threshold bump** (60 → 64)
## How to test
### Details
```bash
cargo test -p anki --lib "notetype::service::tests"
```

## Linked issue
Closes#4839
## Summary / motivation
Adds `cargo-llvm-cov`-based test coverage for the full Rust workspace.
Introduces `just test-rust --coverage` and `just test-rust --coverage
--html`, and wires Rust into the `just test --coverage` umbrella.
`cargo-llvm-cov` is installed on demand into `out/bin/` to avoid
polluting the global cargo install. The `llvm-tools-preview` rustup
component is now installed in CI so the tool can instrument binaries.
## How to test (required)
```sh
# Existing behavior unchanged
just test-rust
# Terminal summary
just test-rust --coverage
# Terminal summary + HTML report under out/coverage/rust/html/
just test-rust --coverage --html
# Umbrella (Rust + Python)
just test --coverage
just test --coverage --html
```
Note: first run of `--coverage` will install `cargo-llvm-cov` into
`out/bin/` (~30s). Subsequent runs skip the install step.
### Checklist
- [x] I ran `./ninja check` or an equivalent relevant check locally.
### Details
- `cargo-llvm-cov` pinned at `0.8.4`, installed into `out/bin/` via
`cargo install --root out`.
- `--workspace --locked` measures all crates and respects the lockfile.
- `llvm-tools-preview` added to `setup-anki` action so CI can instrument
Rust binaries.
- Coverage runs are slower than plain `just test-rust` because
`cargo-llvm-cov` rebuilds with instrumentation — this is expected.
## Before / after behavior
Before: no `just test-rust`, no Rust coverage support.
After: `just test-rust` runs Rust tests via ninja; `just test-rust
--coverage` runs them with `cargo-llvm-cov`
