Snap for 10453563 from a45850c1c21ff9a6cf83e3a1fbc887d5cbf1b026 to mainline-documentsui-release Change-Id: I6f0e3c7a2270bd418c169f8ad9c818490186decd
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(); }
