//! This crate provides an easy way to inline selection of input parameters
//! based on the platform being targeted. Can be used on any `Sized` type.
//!
//! This is guaranteed to be a zero cost abstraction, as all calls are inlined.
//!
//! ```
//! extern crate platform;
//!
//! use platform::Platform;
//!
//! fn main() {
//! println!("Hello from {}!",
//! "unknown"
//! .ios("ios")
//! .android("android")
//! .windows("windows")
//! .macos("macos")
//! .linux("linux")
//! .wasm32("wasm32")
//! .emscripten("emscripten")
//! );
//!
//! // Alternatively, let's pretend the arguments are non-trivial to evaluate.
//! // We can also use this on function pointers so long as all the variants can
//! // coerce to the same function pointer type.
