Snap for 9550733 from a82a8a435e6f4e484005cd49e201591c9945ac2d to mainline-tzdata5-release Change-Id: Ibc40a9253cd57ef345ce2e3e7fcf0892bb14f5af
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(); }
