Snap for 6435660 from db886c6de5269d5f531a02dae75fa35f16dd6855 to sdk-release Change-Id: I64370bf9bcbc338cf81cdeabe26b9e30efb98fa0
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(); }
