Snap for 7160059 from 1280ca5ea6ce05ee3b578a6a66473ff287745d9e to sc-d1-release Change-Id: I8bb8a9cad020dbd781b1ee2ef0eb1a7c2259d093
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(); }
