Mark ab/7061308 as merged in stage. Bug: 180401296 Merged-In: I534a4e272fd8cd41d3f04b091994f84a6af13e67 Change-Id: I753db71f5ba14de1d639e694dce4fbd47bf0eec7
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(); }
