Developer Overview

BarePDF is written entirely in Rust (Edition 2021) and uses a modular Cargo workspace architecture. It combines the high-performance PDFium rendering engine with Slint UI framework for native Windows presentation.

Technology Stack

  • Language: Rust (Stable Edition 2021+).
  • UI Framework: Slint UI (v1.9) with native Win32 platform integration.
  • PDF Engine: Google PDFium via pdfium-render Rust bindings.
  • Background Work / Logging: Crossbeam channels with a single PDFium actor, tracing, and tracing-subscriber.
  • Packaging: Inno Setup (installer) & PowerShell automation.
