NewPipeExtractor (Java) → strawcore (Rust) migration begins. Phase U:
- U-1: Rust toolchain + UniFFI smoke test
- U-2: rustypipe search via uniffi suspend fun, SearchViewModel swapped
What landed:
- rust/strawcore — UniFFI-exported Rust crate using proc-macros.
Builds for arm64-v8a + armeabi-v7a + x86 + x86_64 via cargo-ndk.
Tokio multi-thread runtime singleton drives rustypipe's async API.
- strawApp/build.gradle.kts — cargoBuildHost + cargoBuild + uniffiBindgen
Gradle Exec tasks chained into the Android build. Generated Kotlin
bindings land in src/main/java/uniffi/strawcore/ (gitignored).
- SearchViewModel.kt — calls uniffi.strawcore.search(query) directly.
NewPipeExtractor still in deps for VideoDetail/Player/Channel paths;
those move to Rust in U-3 / U-4.
- Build chain quirks beat:
* cargo absolute path in Exec tasks (PATH wasn't propagating)
* uniffi-bindgen needs UNSTRIPPED host .so — separate cargoBuildHost
builds a debug-profile host lib to read metadata from
* rustypipe rustls-tls-webpki-roots avoids the openssl-sys
cross-compile tarpit
* rquickjs-sys 'bindgen' feature opted in (no prebuilt Android
bindings ship; build-host has libclang 14)
- build-host runtime install (until Dockerfile catches up):
rustup + 4 Android targets + cargo-ndk + NDK r27c. Persists in
/caches/cargo + /caches/android-sdk via the volume mount.
APK size: 22MB (U-1) → 37MB (U-2). libstrawcore.so 3-5MB per ABI carries
rustypipe + reqwest + tokio + rustls + rquickjs. NewPipeExtractor still
in for now (still drives detail + player + channel + feed), so the
Java half is doubled up. U-5 removes it.
