Snap for 11896415 from 5844618d243b032bf12821d9b8e0f6c2ef67b3e9 to 24Q3-release Change-Id: I025b1e3c357970e9b87f67afb9cc1b8cf7cb122b
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(); }
