//! Custom error library support for the `openssl` crate.
//!
//! OpenSSL allows third-party libraries to integrate with its error API. This crate provides a safe interface to that.
//!
//! # Examples
//!
//! ```
//! use openssl_errors::{openssl_errors, put_error};
//! use openssl::error::Error;
//!
//! // Errors are organized at the top level into "libraries". The
//! // openssl_errors! macro can define these.
//! //
//! // Libraries contain a set of functions and reasons. The library itself,
//! // its functions, and its definitions all all have an associated message
//! // string. This string is what's shown in OpenSSL errors.
//! //
//! // The macro creates a type for each library with associated constants for
//! // its functions and reasons.
//! openssl_errors! {
//! pub library MyLib("my cool library") {
//! functions {
//! FIND_PRIVATE_KEY("find_private_key");
//! }
//!
//! reasons {
//! IO_ERROR("IO error");
//! BAD_PASSWORD("invalid private key password");
//! }
//! }
//! }
//!
//! // The put_error! macro pushes errors onto the OpenSSL error stack.
//! put_error!(MyLib::FIND_PRIVATE_KEY, MyLib::BAD_PASSWORD);
//!
//! // Prints `error:80001002:my cool library:find_private_key:invalid private key password:src/lib.rs:27:`
//! println!("{}", Error::get().unwrap());
//!
//! // You can also optionally attach an extra string of context using the
//! // standard Rust format syntax.
//! let tries = 2;
//! put_error!(MyLib::FIND_PRIVATE_KEY, MyLib::IO_ERROR, "tried {} times", tries);
//!
//! // Prints `error:80001001:my cool library:find_private_key:IO error:src/lib.rs:34:tried 2 times`
//! println!("{}", Error::get().unwrap());
//! ```
