 //! Bindings to OpenSSL
-//! 
+//!
 //! This crate provides a safe interface to the popular OpenSSL cryptography library. OpenSSL versions 1.0.1 through
 //! 1.1.1 and LibreSSL versions 2.5 through 2.8 are supported.
-//! 
+//!
 //! # Building
-//! 
+//!
 //! Both OpenSSL libraries and headers are required to build this crate. There are multiple options available to locate
 //! OpenSSL.
-//! 
+//!
 //! ## Vendored
-//! 
+//!
 //! If the `vendored` Cargo feature is enabled, the `openssl-src` crate will be used to compile and statically link to
 //! a copy of OpenSSL. The build process requires a C compiler, perl, and make. The OpenSSL version will generally track
 //! the newest OpenSSL release, and changes to the version are *not* considered breaking changes.
-//! 
+//!
 //! ```toml
 //! [dependencies]
 //! openssl = { version = "0.10", features = ["vendored"] }
 //! ```
-//! 
+//!
 //! The vendored copy will not be configured to automatically find the system's root certificates, but the
 //! `openssl-probe` crate can be used to do that instead.
-//! 
+//!
 //! ## Automatic
-//! 
+//!
 //! The `openssl-sys` crate will automatically detect OpenSSL installations via Homebrew on macOS and vcpkg on Windows.
 //! Additionally, it will use `pkg-config` on Unix-like systems to find the system installation.
-//! 
+//!
 //! ```not_rust
 //! # macOS
 //! $ brew install openssl@1.1
-//! 
+//!
 //! # Arch Linux
 //! $ sudo pacman -S pkg-config openssl
-//! 
+//!
 //! # Debian and Ubuntu
 //! $ sudo apt-get install pkg-config libssl-dev
-//! 
+//!
 //! # Fedora
 //! $ sudo dnf install pkg-config openssl-devel
 //! ```
-//! 
+//!
 //! ## Manual
-//! 
+//!
 //! A set of environment variables can be used to point `openssl-sys` towards an OpenSSL installation. They will
 //! override the automatic detection logic.
-//! 
+//!
 //! * `OPENSSL_DIR` - If specified, the directory of an OpenSSL installation. The directory should contain `lib` and
 //!     `include` subdirectories containing the libraries and headers respectively.
 //! * `OPENSSL_LIB_DIR` and `OPENSSL_INCLUDE_DIR` - If specified, the directories containing the OpenSSL libraries and

 //!
 //! Additionally, these variables can be prefixed with the upper-cased target architecture (e.g.
 //!     `X86_64_UNKNOWN_LINUX_GNU_OPENSSL_DIR`), which can be useful when cross compiling.
-//! 
+//!
 //! # Feature Detection
-//! 
+//!
 //! APIs have been added to and removed from the various supported OpenSSL versions, and this library exposes the
 //! functionality available in the version being linked against. This means that methods, constants, and even modules
 //! will be present when building against one version of OpenSSL but not when building against another! APIs will
 //! document any version-specific availability restrictions.
-//! 
+//!
 //! A build script can be used to detect the OpenSSL or LibreSSL version at compile time if needed. The `openssl-sys`
 //! crate propagates the version via the `DEP_OPENSSL_VERSION_NUMBER` and `DEP_OPENSSL_LIBRESSL_VERSION_NUMBER`
 //! environment variables to build scripts. The version format is a hex-encoding of the OpenSSL release version:
 //! `0xMNNFFPPS`. For example, version 1.0.2g's encoding is `0x1_00_02_07_0`.
-//! 
+//!
 //! For example, let's say we want to adjust the TLSv1.3 cipher suites used by a client, but also want to compile
 //! against OpenSSL versions that don't support TLSv1.3:
-//!
