Merge "Refresh Android.bp, cargo2android.json, TEST_MAPPING." am: ffca6617a5 am: 989fb443a2 am: fbe37b9478 am: 838d3826b6 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/cfg-if/+/1912185 Change-Id: I4390ccf555e6991a2c8961f8c3f3c542a9212400
A macro to ergonomically define an item depending on a large number of #[cfg] parameters. Structured like an if-else chain, the first matching branch is the item that gets emitted.
[dependencies] cfg-if = "0.1"
cfg_if::cfg_if! { if #[cfg(unix)] { fn foo() { /* unix specific functionality */ } } else if #[cfg(target_pointer_width = "32")] { fn foo() { /* non-unix, 32-bit functionality */ } } else { fn foo() { /* fallback implementation */ } } } fn main() { foo(); }
