Import 'cfg-if' package vesion 0.1.10 am: db886c6de5 am: 9ed979c777 am: 2dc946803b am: b33557628f am: f6fcf80bb9 Change-Id: I88f70c1680147078215ad10d504c2c33fb5f4a88
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(); }
