🧹 Nitpick comments (13)
opc_comn_bindings/.metadata/.gitignore (1)
1-2: Use directory-only ignore patterns to avoid accidental file matchesPrefixing with a trailing slash (
/bin/,/obj/) makes it clear you intend to ignore directories, not any file whose name merely contains “bin” or “obj”.-bin -obj +/bin/ +/obj/opc_comn_bindings/.metadata/main.cpp (1)
1-3: Add a short comment clarifying the stub’s purposeA one-liner explaining that this TU exists solely for winmd generation will prevent future confusion and accidental removal.
+#ifdef _MSC_VER +// Stub translation unit required by generate.proj to produce OPCCOMN.winmd. +#endif #include <windows.h> #include "opccomn.h"opc_ae_bindings/.metadata/main.cpp (1)
1-3: Mirror explanatory comment for consistency across binding cratesReplicate the clarification comment added to the COMN stub to keep all metadata TUs self-documenting.
+#ifdef _MSC_VER +// Stub TU for winmd generation (OPC AE interfaces). +#endif #include <windows.h> #include "opc_ae.h"opc_hda_bindings/.metadata/main.cpp (1)
1-3: Consistency: add purpose comment to HDA stub as wellSame rationale as previous files; promotes maintainability.
+#ifdef _MSC_VER +// Stub TU for winmd generation (OPC HDA interfaces). +#endif #include <windows.h> #include "opchda.h"opc_ae_bindings/src/lib.rs (1)
1-3: Consider exposing crate-level documentation
Adding a short//!-level comment describing the purpose of the crate and how the generated bindings are produced will greatly improve discoverability on docs.rs.+//! Rust bindings for OPC AE COM interfaces generated from `OPCAE.winmd`. +//! The bindings are code-generated at build time; see the crate README +//! for regeneration instructions.opc_hda_bindings/src/lib.rs (1)
1-3: Same docstring recommendation as for AE bindings
Replicate a crate-level doc comment to explain purpose and generation process.opc_hda_bindings/README.md (1)
5-10: Replace TODO with a minimal working example
A concrete snippet helps users verify the crate is wired correctly. Example:-```rust -// TODO -``` +```rust +use opc_hda_bindings::*; + +fn main() { + // Obtain `IOPCHDA_SyncRead` from your COM server here… + // let sync_read: IOPCHDA_SyncRead = …; + // println!("Connected to OPC-HDA server: {:?}", sync_read); +} +```opc_comn_bindings/README.md (1)
5-10: Provide a runnable snippet for Common bindings
Showing a simple COM initialisation + interface acquisition pattern will make the docs much more useful.-```rust -// TODO -``` +```rust +use opc_comn_bindings::*; +use windows::Win32::{System::Com::*, System::Ole::CLSCTX_INPROC_SERVER}; + +fn main() -> windows::core::Result<()> { + unsafe { CoInitializeEx(None, COINIT_MULTITHREADED)? }; + // Example: create the OPCEnum CLSID and query `IOPCServerList` + let enum_manager: IOPCServerList = CoCreateInstance(&CLSID_OpcServerList, None, CLSCTX_INPROC_SERVER)?; + println!("Found {} OPC servers", enum_manager.EnumerateClassesOfCategories()?.len()); + Ok(()) +} +```opc_ae_bindings/README.md (1)
7-9: Address the TODO for example code.Consider adding a basic usage example to help users understand how to use the OPC AE bindings.
Would you like me to help generate a basic example once the crate API is stabilized?
opc_ae_bindings/Cargo.toml (1)
5-5: Description copy-paste error (“Historical Data Access” vs AE)The crate is
opc_ae_bindings; the description still says Historical Data Access. Update to “OPC Alarms & Events bindings” to avoid confusion on crates.io.opc_ae_bindings/.metadata/generate.proj (1)
4-6: Hard-coded0.0.0.1WinMD version – consider deriving from crate versionTiny, but keeping metadata and crate versions in sync helps downstream tooling. You can pass
$(PackageVersion)here to avoid manual updates.opc_ae_bindings/build.rs (1)
5-18: Provide actionable error context instead of bareunwrap()Surfacing bindgen failures with context accelerates debugging.
-]) - .unwrap(); +]) + .expect("windows-bindgen failed to generate OPC AE bindings");opc_ae_bindings/.metadata/opc_ae.idl (1)
383-384: String attribute placement is inconsistent with other array parameters.In the version 2 interfaces, the
[string]attribute is placed within the size_is attribute (e.g.,[in, string, size_is(dwNumAreas)]), while in the base interfaces, string parameters use just[in, string]. This inconsistency doesn't affect functionality but could be standardized for clarity.

File: opc_da/src/client/traits/async_io2.rs:94-95
Timestamp: 2024-12-11T01:29:33.264Z
Learning: In `AsyncIo2Trait` within `opc_da/src/client/traits/async_io2.rs`, when directly returning a `Result` from a method like `Refresh2`, it's acceptable to return the result as is without additional wrapping.

File: opc_da/src/client/v3/mod.rs:9-15
Timestamp: 2024-12-10T14:03:29.606Z
Learning: In `windows-rs`, COM interfaces implement `IUnknown`, which automatically calls `Release` when dropped. Therefore, it's unnecessary to manually implement the `Drop` trait to release COM interfaces in structs that hold COM interfaces.

File: opc_da/src/client/unified/group.rs:28-39
Timestamp: 2024-12-10T13:51:14.061Z
Learning: In the `add_items` method in `opc_da/src/client/unified/group.rs`, the OPC DA protocol guarantees that the `results` and `errors` arrays returned will always be of the same length, so additional validation for array length mismatch is not necessary.

File: opc_da/src/client/iterator.rs:114-114
Timestamp: 2024-12-13T18:47:42.521Z
Learning: In `opc_da/src/client/iterator.rs`, when initializing the `cache` array in `GroupIterator`, use `cache: [const { None }; 16]` instead of `cache: [None; 16]` because Flipper requires this change.

Learning: In windows-rs, COM interfaces implement the `Drop` trait via `IUnknown`, automatically releasing resources when they go out of scope, so manual implementation of `Drop` for structs holding COM interfaces is unnecessary.

In opc_ae_bindings/build.rs around lines 2 to 3, the build script only watches
build.rs and the .winmd file for changes, but it should also watch opc_ae.idl
and generate.proj files. Add println! statements for
"cargo:rerun-if-changed=opc_ae.idl" and "cargo:rerun-if-changed=generate.proj"
