Support multi-value fitler and negation filter support for parse and search commands

[digizeph]

Summary

Add multi-value OR filters and negation support for parse and search commands, leveraging bgpkit-parser 0.15.0's new filter capabilities.

New Features

Multi-value filters (OR logic)

Filter by multiple values using comma-separated lists. Elements matching ANY of the specified values are included:

# Match elements from any of these origin ASNs
monocle parse file.mrt -o 13335,15169,8075

# Match any of these prefixes
monocle search -t 2024-01-01 -d 1h -p 1.1.1.0/24,8.8.8.0/24

# Match elements from any of these peer ASNs
monocle parse file.mrt -J 174,2914,3356

Negation filters (exclusion)

Exclude elements using the ! prefix:

# Exclude elements from AS13335
monocle parse file.mrt -o '!13335'

# Exclude elements from multiple ASNs (must all be negated)
monocle search -t 2024-01-01 -d 1h -o '!13335,!15169'

# Exclude specific prefixes
monocle parse file.mrt -p '!1.1.1.0/24,!8.8.8.0/24'

Note: Positive and negative values cannot be mixed in the same filter.

Input validation

Added validation with clear error messages:

• ASN format validation (numeric, optional "AS" prefix)
• Prefix CIDR notation validation
• Negation consistency check (cannot mix ! and non-! values)

Breaking Changes

ParseFilters field types changed to support multiple values:

Field	Before	After
origin_asn	Option<u32>	Vec<String>
prefix	Option<String>	Vec<String>
peer_asn	Option<u32>	Vec<String>

Library users need to update their code:

// Before
let filters = ParseFilters {
    origin_asn: Some(13335),
    ..Default::default()
};

// After
let filters = ParseFilters {
    origin_asn: vec!["13335".to_string()],
    ..Default::default()
};

Other Changes

• Upgraded bgpkit-parser from 0.13.0 to 0.15.0
• Refactored feature gates for the database module to simplify conditional compilation
