From 4472d7914d79966634176458434b1391c5b88167 Mon Sep 17 00:00:00 2001 From: Rishi Jat Date: Sun, 26 Oct 2025 17:14:03 +0530 Subject: [PATCH] feat: Add Scala Native support infrastructure - Create platform abstraction layer (HttpBackend trait) - Extract JVM implementation into JvmHttpBackend using java.net.http.HttpClient - Add placeholder NativeHttpBackend for Scala Native - Refactor Requester to delegate to platform-specific backends - Configure build.mill for cross-compilation (JVM and Native) - Add platform-specific source directories (src-jvm, src-native) - Enable Scala Native 0.5.6 with scala-native-crypto dependency This provides the foundation for Scala Native support (#156). The Native backend implementation requires: - java.net.http.HttpClient for Scala Native - java.net.HttpCookie for Scala Native - Full javax.net.ssl.SSLContext support All JVM functionality remains backward compatible and fully functional. --- build.mill | 34 +- .../src-jvm/requests/JvmHttpBackend.scala | 296 ++++++++++++++++++ .../requests/NativeHttpBackend.scala | 70 +++++
