v0.12.0

Examples and benchmarking

• Added a new runnable example: examples/parse_single_file_parallel.rs.
  • Parses RIB file using thread pool with batching and collecting. Two modes: worker-only parsing (default) or worker
    parsing + element conversion.
  • Includes bottleneck diagnostics, tunable parameters (batch size, workers, etc), benchmarking, and remote file
    downloading.

Breaking changes

• change path_id from u32 to Option<u32> for proper null handling
  • NetworkPrefix::path_id field now properly represents absence with None instead of using 0
  • NetworkPrefix::new() and NetworkPrefix::encode() signatures updated accordingly
  • RibEntry now stores path_id for TABLE_DUMP_V2 messages with AddPath support
  • fixes issue #217

Minumum Supported Rust Version (MSRV)

We now set a minimum supported Rust version (MSRV) of 1.87.0.

Code improvements

New RFCs Supported

• added BGP Flow-Spec parsing support following RFC 8955 and RFC 8956
• added BGP Tunnel Encapsulation attribute parsing support following RFC 9012, RFC 5640, and RFC 8365
• added MRT geo-location extensions support following RFC 6397
• added comprehensive BGP Link-State parsing support following RFC 7752 and extensions
• add support for RFC 8654 Extended Messages
• implemented comprehensive BGP capabilities support for all IANA-defined capability codes with RFC support
• added RFC 8950 support for IPv4 NLRI with IPv6 next-hops
• added RFC 8950 Extended Next Hop capability parsing and encoding
• added RFC 9069 validation warnings for BMP Local RIB peer types

Performance improvements

• optimized BytesMut buffer allocation patterns for better memory efficiency
  • replaced BytesMut::with_capacity() + resize() with BytesMut::zeroed() for cleaner initialization
  • added capacity pre-allocation in ASN encoding to avoid reallocations
  • replaced unnecessary BytesMut allocations with direct slice references in MRT header parsing
  • added capacity pre-allocation in MRT record encoding for optimal buffer sizing
  • fixed non-canonical PartialOrd implementation for ASN type to follow Rust idioms

Iterator improvements

• added fallible iterator implementations for explicit error handling
  • implemented FallibleRecordIterator that returns Result<MrtRecord, ParserErrorWithBytes>
  • implemented FallibleElemIterator that returns Result<BgpElem, ParserErrorWithBytes>
  • added into_fallible_record_iter() and into_fallible_elem_iter() methods on BgpkitParser
  • allows users to handle parsing errors explicitly instead of having them silently skipped
  • maintains full backward compatibility with existing error-skipping iterators
  • reorganized iterator implementations into structured iters module with default and fallible submodules
• added raw MRT record iteration support for record-by-record processing (PR #239, credits to @ties)
  • added RawRecordIterator accessible via into_raw_record_iter() on BgpkitParser
  • separated MRT record reading from parsing for clearer error handling and improved throughput
  • moved RawRecordIterator into dedicated iters::raw module for better organization
  • added raw record parsing to scan_mrt example
  • added tests comparing into_raw_record_iter() with record_iter() behavior
• optimized duplicate BGP attribute detection using a fixed-size boolean array to track seen attributes (PR #237, credits to @ties)
  • added boundary test cases for BGP attribute types

Bug fixes

• fixed TABLE_DUMP_V2 parsing to properly store path_id when AddPath is enabled
  • previously path_id was read but discarded, now properly stored in RibEntry
• fixed BGP OPEN message optional parameter parsing to support multiple capabilities per parameter
  • changed ParamValue::Capability to ParamValue::Capacities(Vec<Capability>) to properly handle RFC 5492 format
  • previously parser only read the first capability in each optional parameter, ignoring subsequent capabilities
  • now correctly parses all capabilities within each optional parameter
  • updated encoding logic to write all capabilities in the vector
• fixed RFC 9072 Extended Optional Parameters Length validation
  • corrected extended parameter format validation (must have non-zero opt_params_len)
  • fixed capability length parsing to always use 1-byte length per RFC 5492, not variable length
  • ensures proper RFC 9072 compliance for extended OPEN message format
• improved RFC 9069 validation for BMP Local RIB peer types
  • fixed multi-protocol capability check to specifically validate MULTIPROTOCOL_EXTENSIONS capability presence
  • previously checked for any capabilities, now correctly validates the required capability type
• added CorruptedBgpMessage error type for better BMP parsing error handling
  • provides more specific error information when BGP messages within BMP are corrupted

Maintenance

• updated dependencies
• updated crate documentation and README
• removed outdated documentation files
