This library reads MaxMind GeoLite2 and GeoIP2 databases.
This library is built using
the Go maxminddb reader.
a fork of geoip2-golagn
All data for the database record is decoded using this library. If you only
need several fields, you may get superior performance by using maxminddb's
Lookup
directly with a result struct that only contains the required fields.
(See example_test.go
in the maxminddb repository for an example of this.)
