//! This crate provides the `Maybe` trait which is implemented for
//! both `T` and `Option<T>`.  The purpose is so that you can write functions
//! like this:
//! ```rs
//! fn foo(param: impl Maybe<Foo>) {
//!     if let Some(value) = param.maybe() {
//!         do_something_with(value)
//!     } else {
//!         do_something_else()
//!     }
//! }
//! ```
//! This way you never need to write `foo(Some(x))`.
