bgpkit-commons 0.10.3

//! # Overview
//!
//! `bgpkit-commons` is a library for common BGP-related data and functions with a lazy-loading
//! architecture. Each module can be independently enabled via feature flags, allowing for minimal builds.
//!
//! ## Quick Start
//!
//! Add `bgpkit-commons` to your `Cargo.toml`:
//!
//! ```toml
//! [dependencies]
//! bgpkit-commons = "0.10"
//! ```
//!
//! All modules follow the same pattern: create a [`BgpkitCommons`] instance, call a `load_xxx()`
//! method to fetch data, then use `xxx_yyy()` methods to access it.
//!
//! ```rust
//! # #[cfg(feature = "bogons")]
//! # fn main() {
//! use bgpkit_commons::BgpkitCommons;
//!
//! let mut commons = BgpkitCommons::new();
//! commons.load_bogons().unwrap();
//!
//! if let Ok(is_bogon) = commons.bogons_match("23456") {
//!     println!("ASN 23456 is a bogon: {}", is_bogon);
//! }
//! # }
//! # #[cfg(not(feature = "bogons"))]
//! # fn main() {}
//! ```
//!
//! ## Modules
//!
//! ### [`asinfo`] — Autonomous System Information
//!
//! Feature: `asinfo` | Sources: RIPE NCC, CAIDA as2org, APNIC population, IIJ IHR hegemony, PeeringDB
//!
//! - Load: `load_asinfo(as2org, population, hegemony, peeringdb)`, `load_asinfo_cached()`, `load_asinfo_with(builder)`
//! - Access: `asinfo_get(asn)`, `asinfo_all()`, `asinfo_are_siblings(asn1, asn2)`
//! - AS name resolution, country mapping, organization data, population statistics, hegemony scores
//!
//! ### [`as2rel`] — AS Relationship Data
//!
//! Feature: `as2rel` | Source: BGPKIT AS relationship inference
//!
//! - Load: `load_as2rel()`
//! - Access: `as2rel_lookup(asn1, asn2)`
//! - Provider-customer, peer-to-peer, and sibling relationships between ASes
//!
//! ### [`bogons`] — Bogon Detection
//!
//! Feature: `bogons` | Source: IANA special registries (IPv4, IPv6, ASN)

//! - Load: `load_bogons()`
//! - Access: `bogons_match(input)`, `bogons_match_prefix(prefix)`, `bogons_match_asn(asn)`, `get_bogon_prefixes()`, `get_bogon_asns()`
//! - Detect invalid/reserved IP prefixes and ASNs that shouldn't appear in routing
//!
//! ### [`countries`] — Country Information
//!
//! Feature: `countries` | Source: GeoNames geographical database
//!
//! - Load: `load_countries()`
//! - Access: `country_by_code(code)`, `country_by_code3(code)`, `country_by_name(name)`, `country_all()`
//! - ISO country code to name mapping and geographical information
//!
//! ### [`mrt_collectors`] — MRT Collector Metadata
//!
//! Feature: `mrt_collectors` | Sources: RouteViews and RIPE RIS official APIs
//!
//! - Load: `load_mrt_collectors()`, `load_mrt_collector_peers()`
//! - Access: `mrt_collectors_all()`, `mrt_collectors_by_name(name)`, `mrt_collectors_by_country(country)`, `mrt_collector_peers_all()`, `mrt_collector_peers_full_feed()`
//! - BGP collector information, peer details, full-feed vs partial-feed classification
//!
//! ### [`rpki`] — RPKI Validation
//!
//! Feature: `rpki` | Sources: Cloudflare (real-time), RIPE NCC historical, RPKIviews historical, RPKISPOOL historical
//!
//! - Load: `load_rpki(optional_date)`, `load_rpki_historical(date, source)`, `load_rpki_from_files(urls, source, date)`
//! - Access: `rpki_validate(asn, prefix)`, `rpki_validate_check_expiry(asn, prefix, timestamp)`, `rpki_lookup_by_prefix(prefix)`, `rpki_lookup_aspa(customer_asn)`
//! - Route Origin Authorization (ROA) and ASPA validation, supports real-time and historical sources
//!
//! ## Examples
//!
//! ### Loading multiple modules
//!
//! ```rust
//! # #[cfg(all(feature = "asinfo", feature = "countries"))]
//! # fn main() {
//! use bgpkit_commons::BgpkitCommons;
//!
//! let mut commons = BgpkitCommons::new();
//! commons.load_asinfo(false, false, false, false).unwrap();
//! commons.load_countries().unwrap();
//!
//! if let Ok(Some(asinfo)) = commons.asinfo_get(13335) {
//!     println!("AS13335: {} ({})", asinfo.name, asinfo.country);
//! }
//! # }
//! # #[cfg(not(all(feature = "asinfo", feature = "countries")))]
//! # fn main() {}
//! ```
//!
//! ### Using AsInfoBuilder
//!
//! ```rust
//! # #[cfg(feature = "asinfo")]
//! # fn main() {
//! use bgpkit_commons::BgpkitCommons;
//!
//! let mut commons = BgpkitCommons::new();
//! let builder = commons.asinfo_builder()
//!     .with_as2org()
//!     .with_peeringdb();
//! commons.load_asinfo_with(builder).unwrap();
//!
//! if let Ok(are_siblings) = commons.asinfo_are_siblings(13335, 132892) {
//!     println!("AS13335 and AS132892 are siblings: {}", are_siblings);
//! }
//! # }
//! # #[cfg(not(feature = "asinfo"))]
//! # fn main() {}
//! ```
//!
//! ### Loading historical RPKI data
//!
//! ```rust,no_run
//! # #[cfg(feature = "rpki")]
//! # fn main() {
//! use bgpkit_commons::BgpkitCommons;
//! use bgpkit_commons::rpki::{HistoricalRpkiSource, RpkiViewsCollector};
//! use chrono::NaiveDate;
//!
//! let mut commons = BgpkitCommons::new();
//! let date = NaiveDate::from_ymd_opt(2024, 1, 4).unwrap();
//!
//! // Load from RIPE NCC historical archives
//! commons.load_rpki_historical(date, HistoricalRpkiSource::Ripe).unwrap();
//!
//! // Or load from RPKIviews collectors
//! let source = HistoricalRpkiSource::RpkiViews(RpkiViewsCollector::KerfuffleNet);
//! commons.load_rpki_historical(date, source).unwrap();
//!
//! // List available files for a date
//! let files = commons.list_rpki_files(date, HistoricalRpkiSource::Ripe).unwrap();
//! # }
//! # #[cfg(not(feature = "rpki"))]
//! # fn main() {}
//! ```
//!
//! ### Direct module access
//!
//! Modules can also be used directly without `BgpkitCommons`:
//!
//! ```rust
//! # #[cfg(feature = "bogons")]
//! # fn main() {
//! use bgpkit_commons::bogons::Bogons;
//! let bogons = Bogons::new().unwrap();
//! # }
//! # #[cfg(not(feature = "bogons"))]
//! # fn main() {}
//! ```
//!
//! ## Feature Flags
//!
//! | Feature | Description |
//! |---------|-------------|
//! | `asinfo` | AS information: names, countries, organizations, population, hegemony |
//! | `as2rel` | AS relationship data |
//! | `bogons` | Bogon prefix and ASN detection |
//! | `countries` | Country information lookup |
//! | `mrt_collectors` | MRT collector metadata |
//! | `rpki` | RPKI validation (ROA and ASPA) |
//! | `all` *(default)* | Enables all modules |
//!
//! For a minimal build:
//!
//! ```toml
//! [dependencies]
//! bgpkit-commons = { version = "0.10", default-features = false, features = ["bogons", "countries"] }
//! ```
