Documentation

Overview

Package geodata includes utilities to decode and parse the geoip & geosite dat files.

It relies on the proto structure of GeoIP, GeoIPList, GeoSite and GeoSiteList in github.com/v2fly/v2ray-core/v4/app/router/config.proto to comply with following rules:

1. GeoIPList and GeoSiteList cannot be changed
2. The country_code in GeoIP and GeoSite must be a length-delimited `string`(wired type) and has field_number set to 1
