Snap for 7152399 from c38249f0169b4a00f07ebaab133afbb6c3352716 to sc-d1-release Change-Id: I77227886b31bd9cd04cbb9f0a0e49f3996f25da6
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(); }
