Snap for 8564071 from b1ee0ccbff33d19ad765f5b8da493d0f9473f82b to mainline-extservices-release Change-Id: I1927e3757b522849548f22e807c72d9b0fa2b12c
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(); }
