v0.4.0

Fix within() bugs that caused nodes skipping:

• When startNode() returns a data pointer, the code skipped it because of "if (node < node_count)".
• When traversing the prefix, if a data record is encountered before exhausting all prefix bits (querying /24 but record is at /23), the code skipped the data pointer.

Add IP address validation to within() and lookup: when IPv6 address was used on IPv4-only database, the results could be garbage, so such address is rejected now.

v0.2.0

Changelog

• Network.parse was added to parse CIDR
• Fields filtering was added to speed up decoding. Note, lookup and within now expect Options struct.

const fields = maxminddb.Fields.from(maxminddb.geolite2.City, &.{ "city", "country" });
const city = try db.lookup(allocator, maxminddb.geolite2.City, &ip, .{ .only = fields });

Basic features

This release provides:

• basic features found in Go/Rust libraries such as lookup by IP and network traversal
• safety checks seen in Go/Rust libraries
• compliance with the MaxMind DB spec, e.g., the requirement for struct fields to match database field order requirement was removed from the library
