Wry is a cross-platform Rust library for embedding native webviews into desktop and mobile applications. It is not a standalone application but a composable crate used by projects like Tauri. The code exposes a builder-pattern API (`WebViewBuilder` -> `WebView`) with `WebContext`, custom protocol handlers, an async IPC bridge, permissions, downloads, cookies, and platform extension traits. Production behavior is split across four backends: WebView2 on Windows, WKWebView on macOS/iOS, WebKitGTK on Linux, and Android WebView through JNI/Kotlin. All backends implement the same high-level operations but use platform-specific mechanisms (COM, Objective-C runtime, GTK signals, JNI pipes) with conditionally compiled code. Primary data flows are page loading from URLs or HTML, custom scheme requests handled as `http::Request`/`Response`, and JavaScript-to-Rust IPC via an injected `window.ipc.postMessage` bridge. The crate also supports drag-and-drop, permission requests, streaming media through custom protocols, and initialization scripts injected before page load. Most platform differences are isolated behind extension traits, allowing downstream users to add platform-specific behavior without polluting the core API. Maintenance is active, with frequent releases, cross-platform CI, Miri tests, performance benchmarks, and a covector-driven release process. However, the codebase carries notable drift risk: private macOS APIs, version-gated workarounds, Cargo audit ignores tied to an older MSRV, some Android toolchain pins in documentation, and an in-progress migration to Rust 2024 edition. Despite these risks, engineering quality is strong: the custom protocol workaround, main-thread dispatch utility, and permission normalization layers are clean examples of hard-won platform integration patterns.
