/* private fields */
}
Expand description
A reader for the MaxMind DB format. The lifetime 'data
is tied to the lifetime of the underlying buffer holding the contents of the database file.

impl Reader<Vec<u8>>
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>(&'de self, address: IpAddr) -> Result<T, MaxMindDBError>where
T: Deserialize<'de>,
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);

T: Deserialize<'de>,
pub fn lookup_prefix<T>(
&'de self,
address: IpAddr
) -> Result<(T, usize), MaxMindDBError>where
T: Deserialize<'de>,
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 = "89.160.20.128".parse().unwrap();
let (city, prefix_len) = reader.lookup_prefix::<geoip2::City>(ip).unwrap();

T: Deserialize<'de>,
pub fn within<T>(
&'de self,
cidr: IpNetwork
) -> Result<Within<'_, T, S>, MaxMindDBError>where
T: Deserialize<'de>,
Iterate over blocks of IP networks in the opened MaxMind DB
Example:
use ipnetwork::IpNetwork;
use maxminddb::{geoip2, Within};
let reader = maxminddb::Reader::open_readfile("test-data/test-data/GeoIP2-City-Test.mmdb").unwrap();
let ip_net = IpNetwork::V6("::/0".parse().unwrap());
let mut iter: Within<geoip2::City, _> = reader.within(ip_net).unwrap();
while let Some(next) = iter.next() {
let item = next.unwrap();
println!("ip_net={}, city={:?}", item.ip_net, item.info);
