//! A certificate store abstraction.
//!
//! This crates provides a unified interface for different certificate
//! stores via the [`Store`] and [`StoreUpdate`] traits. It also
//! provides a number of helper functions and data structures, like
//! [`UserIDIndex`] to help implement this functionality.
//!
//! [`UserIDIndex`]: store::UserIDIndex
//!
//! The [`CertStore`] data structure combines multiple certificate
//! backends in a transparent way to users.
//!
//! # Examples
//!
//! We can store certificates in an in-memory store, and query the store:
//!
//! ```rust
//! use std::sync::Arc;
//! use sequoia_openpgp::cert::{Cert, CertBuilder};
//! use sequoia_cert_store::{CertStore, LazyCert, Store, StoreUpdate};
//!
//! # fn main() -> anyhow::Result<()> {
//! // Create an in-memory certificate store. To use the default
//! // on-disk certificate store, use `CertStore::new`.
//! let mut certs = CertStore::empty();
//!
//! let (cert, _rev) = CertBuilder::new().generate()?;
//! let fpr = cert.fingerprint();
//!
//! // It's not in the cert store yet:
//! assert!(certs.lookup_by_cert_fpr(&fpr).is_err());
//!
//! // Insert a certificate. If using a backing store, it would
//! // also be written to disk.
//! certs.update(Arc::new(LazyCert::from(cert)))?;
//!
//! // Make sure it is there.
//! let cert = certs.lookup_by_cert_fpr(&fpr).expect("present");
//! assert_eq!(cert.fingerprint(), fpr);
//!
//! // Resolve the `LazyCert` to a `Cert`. Certificates are stored
//! // using `LazyCert` so that it is possible to work with `RawCert`s
//! // and `Cert`s. This allows the implementation to defer fully parsing
//! // and validating the certificate until it is actually needed.
//! let cert: &Cert = cert.to_cert()?;
//! # Ok(()) }
//! ```
//!
//! We can use the same API on a persistent certificate store, kept on the
//! filesystem:
//!
//! ```rust
//! use std::fs;
//! # use tempfile;
//! #
//! # use std::sync::Arc;
//! #
//! # use sequoia_openpgp as openpgp;
//! # use openpgp::Result;
//! # use openpgp::cert::{Cert, CertBuilder};
//! #
//! # use sequoia_cert_store::{CertStore, LazyCert, Store, StoreUpdate};
//!
//! # fn main() -> Result<()> {
//! // Make a certificate store on the file system, in a fresh empty directory.
//! let directory = "/tmp/test-sequoia-certificate-directory";
//! # let directory_object = tempfile::tempdir()?; let directory = directory_object.path();
//! fs::create_dir_all(directory)?;
//! let mut store = CertStore::open(directory)?;
//!
//! // Make a new certificate.
//! let (cert, _rev) = CertBuilder::new().generate()?;
//! let fpr = cert.fingerprint();
//!
//! // The certificate of course will not be in the store yet.
//! assert!(store.lookup_by_cert_fpr(&fpr).is_err());
//!
//! // Add it.
//! store.update(Arc::new(LazyCert::from(cert)))?;
//!
//! // Now the certificate can be found.
//! let found = store.lookup_by_cert_fpr(&fpr).expect("present");
//! assert_eq!(found.fingerprint(), fpr);
//!
//! // Again, we can resolve the `LazyCert` to a `Cert`.
//! let cert: &Cert = found.to_cert()?;
//! # Ok(()) }
//! ```
