is tied to the lifetime of the underlying buffer holding the contents of the database file.

sourcepub fn open_readfile<P: AsRef<Path>>(
database: P
) -> Result<Reader<Vec<u8>>, MaxMindDBError>
pub fn open_readfile<P: AsRef<Path>>(
database: P
) -> Result<Reader<Vec<u8>>, MaxMindDBError>
Open a MaxMind DB database file by loading it into memory.
Example
let reader = maxminddb::Reader::open_readfile("test-data/test-data/GeoIP2-City-Test.mmdb").unwrap();

pub fn lookup<T>(&self, address: IpAddr) -> Result<T, MaxMindDBError>where

Lookup the socket address in the opened MaxMind DB
Example:
use maxminddb::geoip2;
use std::net::IpAddr;
use std::str::FromStr;
let reader = maxminddb::Reader::open_readfile("test-data/test-data/GeoIP2-City-Test.mmdb").unwrap();
let ip: IpAddr = FromStr::from_str("89.160.20.128").unwrap();
let city: geoip2::City = reader.lookup(ip).unwrap();
print!("{:?}", city);
