Struct Db

pub struct Db(/* private fields */);

ASN record database that is optimized for lookup by an IP address.

Implementations

impl Db

pub fn form_tsv(data: impl Read) -> Result<Db, DbError>

Loads database from ASN data as provided by IPtoASN - the only supported file format is of ip2asn-v4.tsv file.

pub fn load(db_data: impl Read) -> Result<Db, DbError>

Loads database from the binary index that was stored with .store() - this method is much faster than loading from the TSV file.

pub fn store(&self, db_data: impl Write) -> Result<(), DbError>

Stores database as a binary index for fast loading with .load().

pub fn lookup(&self, ip: Ipv4Addr) -> Option<&Record>

Performs lookup by an IP address for the ASN Record of which network this IP belongs to.

Trait Implementations

impl Debug for Db

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
