//! 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
//! use openssl::x509::store::{X509StoreBuilder, X509Store};
//! use openssl::x509::{X509, X509Name};
//! use openssl::pkey::PKey;
//! use openssl::hash::MessageDigest;
//! use openssl::rsa::Rsa;
//! use openssl::nid::Nid;
//!
//! let rsa = Rsa::generate(2048).unwrap();
//! let pkey = PKey::from_rsa(rsa).unwrap();
//!
//! let mut name = X509Name::builder().unwrap();
//! name.append_entry_by_nid(Nid::COMMONNAME, "foobar.com").unwrap();
//! let name = name.build();
//!
//! let mut builder = X509::builder().unwrap();
//! builder.set_version(2).unwrap();
//! builder.set_subject_name(&name).unwrap();
//! builder.set_issuer_name(&name).unwrap();
//! builder.set_pubkey(&pkey).unwrap();
//! builder.sign(&pkey, MessageDigest::sha256()).unwrap();
//!
//! let certificate: X509 = builder.build();
//!
//! let mut builder = X509StoreBuilder::new().unwrap();
//! let _ = builder.add_cert(certificate);
//!
//! let store: X509Store = builder.build();
//! ```
