Moved the file tree creation logic entirely to the Rust backend as requested.

Changes:

  • Added urlencoding crate dependency.
  • Implemented build_file_tree in apps/app/src-tauri/src/lib.rs.
  • Updated apps/app/src/lib/file_tree/builder.ts to use the new command.
  • Ensured cross-platform compatibility for Desktop and Android (replicating Android specific URI construction).

feat(filetree): move file tree generation logic to Rust backend
4de427c 
Migrates the recursive file tree building logic from the TypeScript frontend to the Rust backend to improve performance, especially for large directories.

- Implements `build_file_tree` Tauri command in Rust.
- Adds Desktop implementation using `std::fs` and `spawn_blocking`.
- Adds Android implementation using `tauri-plugin-android-fs` and `urlencoding`.
- Updates frontend `builder.ts` to invoke the Rust command.
- Preserves existing filtering logic (markdown files only, ignore hidden dirs).

perf: optimize file tree building and sorting in Rust
9e0502e 
- Move sorting logic inside `spawn_blocking` to avoid blocking the main thread on large directories.
- Fix compiler warnings (unused imports/variables).
- Ensure correct recursion and sorting on both Desktop and Android.
- Refactor argument names to avoid unused variable warnings across platforms.

feat(filetree): move generation and sorting to Rust backend
bc12921 
Migrates file tree logic to Rust to improve performance and prevent UI freezes.
- Implements `build_file_tree` and `sort_file_tree` Tauri commands in `src-tauri/src/lib.rs`.
- Uses `spawn_blocking` to offload heavy operations from the main thread.
- Ensures compatibility with Android FS plugin (fixing compilation issues) and Desktop `std::fs`.
- Updates frontend to invoke Rust commands and safely handle auto-sorting in `$effect` without infinite loops.
- Adds `urlencoding` dependency for Android path handling.
- Cleans up deprecated JS logic.

fix: don't use rust sort function for subsequent sorts bcuz of latenc…

…y and less flexibility

so, calling rust sort function everytime for subsequent sorting seems to
have incresed latency.
also on rename or any file tree changes, the sorting was commented out.

  • Moved the file tree creation to rust and calling that through tauri command interface
  • moved the file tree ts modules to the directory apps/app/src/lib/file_tree

Acknowledged. I have implemented these changes. I have moved the file tree creation to Rust backend, implementing both Desktop and Android support with optimizations (parallelism on Android). I also ensured that sorting is handled in Rust initially but subsequent updates are handled synchronously in JS as requested.

perf(filetree): optimize Android file tree building in Rust
02f93b5 
- Move file tree generation to Rust backend using `tauri-plugin-android-fs` for Android and `std::fs` for Desktop.
- Optimize Android implementation by using `read_dir_with_options` to fetch minimal metadata and parallelizing recursion with `futures::future::join_all`.
- Use `spawn_blocking` on Desktop to avoid blocking the main thread.
- Perform initial tree sorting in Rust.
- Keep subsequent UI sorting in JavaScript to ensure instant feedback and avoid round-trips for small updates (renames, etc.).
- Fix Android compilation issues and unused variable warnings.
- Add `urlencoding` and `futures` crate dependencies.
