//! Describe a context in which to verify an `X509` certificate.
//!
//! The `X509` certificate store holds trusted CA certificates used to verify
//! peer certificates.
//!
//! # Example
//!
//! ```rust
//! extern crate openssl;
//!
//! use openssl::x509::X509;
//! use openssl::x509::store::{X509StoreBuilder, X509Store};
//!
//! fn main() {
//! let cert = include_bytes!("cert.pem");
//! let cert = X509::from_pem(cert).ok().expect("Failed to load PEM");
//!
//! let mut builder = X509StoreBuilder::new().unwrap();
//! let _ = builder.add_cert(cert);
//!
//! let store: X509Store = builder.build();
//! }
//! ```
