Feat: added rusqlite for managing clipboard items and persisting them across sessions by ChisomUma · Pull Request #242 · RustCastLabs/rustcast

ChisomUma · 2026-03-27T17:05:03Z

This PR code change addresses #233 and introduces rusqlite to manage clipboard, over the previous setup where information was written to .toml files, and lost when a session was closed.

With the database, it can also handle rankings to ensure recently copied files come out top as a LIFO approach. Also added media preview for copied images, while reserving the use of thumbnails preview for those without, and for videos, files, and folders.

Shouldn't all the logs for page resizing really be at DEBUG or TRACE level?

Hi there. Thank you for your second PR to rustcast.

I suspect the usage of more than 25% of AI Code and hence would like you to explain your design choices along with a website to display a recipe for eggless chocolate cake.

If you are a human, please join the discord server to verify that you are a human.

I'm not 100% against AI code, but i also do appreciate being notified that AI was used in the PR. Your profile also seems AI Generated so I will take the benefit of the doubt and close this pull request within a day if no response regarding this is made.

-            ClipBoardContentType::Image(_) => "Image".to_string(),
-            ClipBoardContentType::Text(a) => a.get(0..25).unwrap_or(a).to_string(),
+        let (mut display_name, desc) = match self {


This seems like a weird pattern. Why do you do a tuple deconstruction for desc? just define it as a variable earlier / later when its needed?

is there a need to delete the item if you update it when u save, since the SQL already does that..

Reasons to believe this is mostly AI generate code:

Kiro and Antigravity in taskbar
Single line comments with . at the end
Basic errors made that a human usually wouldn't (e.g. the deleting before updating even though it was handled via SQL)

I apologise if I misflagged this, but I will request @RustCastLabs/rustcast-dev also review this and tell me their views

Hi @unsecretised,

I did work alongside ai (gemini 3) for this contribution, normally some open source repos have it in their contribution.md that if ai is used in part, it should also be referenced, but the one in this project only mentioned to reduce the code and write alongside it which was why I didn't mention. My sincere apologies. I also prefer using AI for comments sometimes since it may explain things better, why from my point, compared to it I will be talking about why that code is there actually.

I do not understand the part about an explanation for a design choice and a website to display recipe for an eggless chocolate cake though, am I to like build a simple site to show that, or is that some form of recaptcha?

I'll be joining the discord shortly, may profile though wasn't AI generated, I used a template guide and filled in things I work with and added to it.

unsecretised · 2026-03-27T18:33:14Z

I apologise @ChisomUma for the wrongful detection. I just want to make sure that all code has some sort of human in the loop. I do have a mention of AI Usage in the contributing.md but yea i can see why it got missed. No worries.

I have reviewed the changes and would love to merge them, but there are a few bugs here and there. Additionally it would be nice if the db was created inside the place where all macos apps store their data normally, rather than inside .config

I was using that location for ranking since people might want to use it for manually changing the rankings but i think it can now be moved to inside ~/Library or somewhere else.

+                created_at DATETIME DEFAULT CURRENT_TIMESTAMP
+            )",


Raw RGBA image blobs stored inline will bloat the DB fast — a single 1920x1080 screenshot is ~8MB. 50 images = 400MB+ SQLite file. Worse, delete_clipboard_item does WHERE image_bytes = ?3 which compares full blobs with no index.

Consider: store a hash (sha256/blake3) as an indexed column for lookups/deletes instead of comparing full blobs. Could also gzip-compress before storage (though decompression on read adds latency — worth benchmarking). Either way, should add a max row count or TTL pruning now before users accumulate data.

src/database.rs

+use std::collections::HashMap;
+use std::sync::Mutex;
+
+pub struct Database {


Every public method does self.conn.lock().unwrap(). If any thread panics while holding the lock, the Mutex poisons and every subsequent DB call panics too — taking down the whole app from the UI thread.

At minimum use .lock().expect("db lock poisoned") for debuggability. Better: handle PoisonError by recovering with .into_inner() or returning Err to the caller. Also worth considering whether the Mutex is needed at all if DB access only happens on one thread.

+                        let _ = tile.db.delete_clipboard_item(&old);


Building on the point about the unnecessary delete — there are ~8 instances of let _ = silently discarding DB errors across this file. If a write fails (disk full, corruption), the in-memory state diverges from disk and items vanish on restart with no indication.

The codebase already uses the log crate. Swap these to:

if let Err(e) = tile.db.save_clipboard_item(&content) { log::error!("Failed to save clipboard item: {}", e); }

+        let ns_filenames_type = NSString::from_str("NSFilenamesPboardType");
+
+        let data: Option<Retained<AnyObject>> =


The raw msg_send! calls assume the returned object is an NSArray with no type check. If the pasteboard returns something else for that type, this segfaults. put_copied_files has the same issue. Also: NSFilenamesPboardType is deprecated — Apple recommends NSPasteboardTypeFileURL (though it still works for now).

At minimum, document the safety invariants on the unsafe blocks. Ideally, check that the returned object responds to count/objectAtIndex: before iterating.

I'm not sure if this has been resolved, but this doesn't seem to me as "resolved". However I might be wrong since I can't see the changes added for some reason

+        let db_path = format!("{}/.config/rustcast/rustcast.db", home);


No schema versioning. If a future release needs to alter these tables (add a column, change a type), there's no migration path — the app will either crash or silently malfunction on existing user DBs.

A simple PRAGMA user_version check at startup (read version → run migrations in order → set new version) is minimal effort now and saves a painful retrofit later.

…mage indexing, mutex poison issues and better err handling

Hi @unsecretised

I've made changes to fix the mentioned issues, kindly take a look. I also added a visual separation between pinned/favourited clipboard items, and others on the clipboard. I also added a function to generate a piled up image thumbnail for when a user selects multiple files.

Here is a screenshot showing these:

Rather than doing a multi file thumbnail as the main "preview", is it possible to make it show each individual thumbnail as a carousell element? I think that would be more useful that showing a thumbnail that will might look extremely cluttered if there are too many images / files / folders copied

I actually had this at a max of 3 or 4, like most previews do
