Crate rustbgpd_wire 

rustbgpd-wire — BGP message codec

Pure codec library for BGP message encoding and decoding. Zero internal dependencies. This crate is independently publishable.

Message Types

• OpenMessage — BGP OPEN with capability negotiation
• NotificationMessage — BGP NOTIFICATION with error codes
• UpdateMessage — BGP UPDATE (wire-level framing, raw bytes in M0)
• Keepalive — represented as Message::Keepalive unit variant

Entry Points

• decode_message — decode a complete BGP message from bytes
• encode_message — encode a BGP message to bytes
• peek_message_length — check if a complete message is available (for transport framing)

Invariants

• Maximum message size: 4096 bytes (RFC 4271 §4.1)
• No panics on malformed input — all paths return Result
• No unsafe code
