Upgrade rust/crates/cfg-if to 1.0.0 am: 70032b60de am: a4e6ae480a am: b72d7218c0 am: 4e70b0bd2a Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/cfg-if/+/1474936 Change-Id: Iad86852ea492805862aeb05e9d70f83162872299
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(); }
