Merge sc-qpr1-dev-plus-aosp-without-vendor@7810918 Bug: 205056467 Merged-In: I1bd91bc5f1679dae4ff6af8377dff700b0c4a55a Change-Id: I7c550f8e902e3a08de0a2f65f15693effbd24af6
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(); }
