+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.

+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must

+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents

+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+//! A framework for Rust wrappers over C APIs.
+//!
+//! Ownership is as important in C as it is in Rust, but the semantics are often implicit. In
+//! particular, pointer-to-value is commonly used to pass C values both when transferring ownership
+//! or a borrow.
+//!
+//! This crate provides a framework to define a Rust wrapper over these kinds of raw C APIs in a way
+//! that allows ownership semantics to be expressed in an ergonomic manner. The framework takes a
+//! dual-type approach similar to APIs in the standard library such as `PathBuf`/`Path` or `String`/
+//! `str`. One type represents an owned value and references to the other represent borrowed
+//! values.
+//!
+//! # Examples
+//!
+//! ```
+//! use foreign_types::{ForeignType, ForeignTypeRef, Opaque};
+//! use std::ops::{Deref, DerefMut};
+//! use std::ptr::NonNull;
+//!
+//! mod foo_sys {
+//!     pub enum FOO {}
+//!
+//!     extern {
+//!         pub fn FOO_free(foo: *mut FOO);
+//!     }
+//! }
+//!
+//! // The borrowed type is a newtype wrapper around an `Opaque` value.
+//! //
+//! // `FooRef` values never exist; we instead create references to `FooRef`s
+//! // from raw C pointers.
+//! pub struct FooRef(Opaque);
+//!
+//! unsafe impl ForeignTypeRef for FooRef {
+//!     type CType = foo_sys::FOO;
+//! }
+//!
+//! // The owned type is simply a newtype wrapper around the raw C type.
+//! //
+//! // It dereferences to `FooRef`, so methods that do not require ownership
+//! // should be defined there.
+//! pub struct Foo(NonNull<foo_sys::FOO>);
+//!
+//! unsafe impl Sync for FooRef {}
+//! unsafe impl Send for FooRef {}
+//!
+//! unsafe impl Sync for Foo {}
+//! unsafe impl Send for Foo {}
+//!
+//! impl Drop for Foo {
+//!     fn drop(&mut self) {
+//!         unsafe { foo_sys::FOO_free(self.as_ptr()) }
+//!     }
+//! }
+//!
+//! unsafe impl ForeignType for Foo {
+//!     type CType = foo_sys::FOO;
+//!     type Ref = FooRef;
+//!
+//!     unsafe fn from_ptr(ptr: *mut foo_sys::FOO) -> Foo {
+//!         Foo(NonNull::new_unchecked(ptr))
+//!     }
+//!
+//!     fn as_ptr(&self) -> *mut foo_sys::FOO {
+//!         self.0.as_ptr()
+//!     }
+//!
+//!     fn into_ptr(self) -> *mut foo_sys::FOO {
+//!         let inner = self.as_ptr();
+//!         ::core::mem::forget(self);
+//!         inner
+//!     }
+//! }
+//!
+//! impl Deref for Foo {
+//!     type Target = FooRef;
+//!
+//!     fn deref(&self) -> &FooRef {
+//!         unsafe { FooRef::from_ptr(self.as_ptr()) }
+//!     }
+//! }
+//!
+//! impl DerefMut for Foo {
+//!     fn deref_mut(&mut self) -> &mut FooRef {
+//!         unsafe { FooRef::from_ptr_mut(self.as_ptr()) }
+//!     }
+//! }
+//!
+//! // add in Borrow, BorrowMut, AsRef, AsRefMut, Clone, ToOwned...
+//! ```
+//!
+//! The `foreign_type!` macro can generate this boilerplate for you:
+//!
+//! ```
+//! use foreign_types::foreign_type;
+//!
+//! mod foo_sys {
+//!     pub enum FOO {}
+//!
+//!     extern {
+//!         pub fn FOO_free(foo: *mut FOO);
+//!         pub fn FOO_duplicate(foo: *mut FOO) -> *mut FOO; // optional
+//!     }
+//! }
+//!
+//! foreign_type! {
+//!     /// A Foo.
+//!     pub unsafe type Foo
+//!         : Sync + Send // optional
+//!     {
+//!         type CType = foo_sys::FOO;
+//!         fn drop = foo_sys::FOO_free;
+//!         fn clone = foo_sys::FOO_duplicate; // optional
+//!     }
+//!
+//!     /// A Foo with generic parameters.
+//!     pub unsafe type GenericFoo<T> {
+//!         type CType = foo_sys::FOO;
+//!         // This type is added as a `PhantomData` field to handle variance
+//!         // of the parameters. However, it has no impact on trait impls:
+//!         // `GenericFoo<T>` is always `Clone`, even if `T` is not.
+//!         type PhantomData = T;
+//!         fn drop = foo_sys::FOO_free;
+//!         fn clone = foo_sys::FOO_duplicate;
+//!     }
+//! }
+//!
+//! # fn main() {}
+//! ```
+//!
+//! If `fn clone` is specified, then it must take `CType` as an argument and return a copy of it as `CType`.
+//! It will be used to implement `Clone`, and if the `std` Cargo feature is enabled, `ToOwned`.
+//!
+//! Say we then have a separate type in our C API that contains a `FOO`:
+//!
+//! ```
+//! mod foo_sys {
+//!     pub enum FOO {}
+//!     pub enum BAR {}
+//!
+//!     extern {
+//!         pub fn FOO_free(foo: *mut FOO);
+//!         pub fn BAR_free(bar: *mut BAR);
+//!         pub fn BAR_get_foo(bar: *mut BAR) -> *mut FOO;
+//!     }
+//! }
+//! ```
+//!
+//! The documentation for the C library states that `BAR_get_foo` returns a reference into the `BAR`
+//! passed to it, which translates into a reference in Rust. It also says that we're allowed to
+//! modify the `FOO`, so we'll define a pair of accessor methods, one immutable and one mutable:
+//!
+//! ```
+//! use foreign_types::{ForeignTypeRef, foreign_type};
+//!
+//! mod foo_sys {
+//!     pub enum FOO {}
+//!     pub enum BAR {}
+//!
+//!     extern {
+//!         pub fn FOO_free(foo: *mut FOO);
+//!         pub fn BAR_free(bar: *mut BAR);
+//!         pub fn BAR_get_foo(bar: *mut BAR) -> *mut FOO;
+//!     }
+//! }
+//!
+//! foreign_type! {
+//!     /// A Foo.
+//!     pub unsafe type Foo: Sync + Send {
+//!         type CType = foo_sys::FOO;
+//!         fn drop = foo_sys::FOO_free;
+//!     }
+//!
+//!     /// A Bar.
+//!     pub unsafe type Bar: Sync + Send {
+//!         type CType = foo_sys::BAR;
+//!         fn drop = foo_sys::BAR_free;
+//!     }
+//! }
+//!
+//! impl BarRef {
+//!     fn foo(&self) -> &FooRef {
+//!         unsafe { FooRef::from_ptr(foo_sys::BAR_get_foo(self.as_ptr())) }
+//!     }
+//!
+//!     fn foo_mut(&mut self) -> &mut FooRef {
+//!         unsafe { FooRef::from_ptr_mut(foo_sys::BAR_get_foo(self.as_ptr())) }
