From 872d579a22cd8e2d34a9baf8d892346e4ac71d27 Mon Sep 17 00:00:00 2001 From: Ivan Lozano Date: Wed, 23 Mar 2022 17:31:39 -0400 Subject: rust: rust_proc_macro host snapshot support. Adds support for capturing rust_proc_macros as part of the host snapshot. Proc macros target the host and can be thought of as compiler plugins. Because of this, they don't have vendor image variants and can't be easily captured as part of the vendor snapshot. Instead we capture them as part of the host snapshot. This adds a rust_prebuilt_proc_macro module type. Bug: 204304380 Test: m HOST_FAKE_SNAPSHOT_ENABLE=true host-fake-snapshot dist Test: python3 development/vendor_snapshot/update.py --image=host --install-dir=vendor/vendor_name/ 31 --local out/dist Test: Checked Android.bp for rust_prebuilt_proc_macro modules.
