Crate icann_rdap_client

ICANN RDAP Client Library

This is a client library for the Registration Data Access Protocol (RDAP) written and sponsored by the Internet Corporation for Assigned Names and Numbers (ICANN). RDAP is standard of the IETF, and extensions to RDAP are a current work activity of the IETF’s REGEXT working group. More information on ICANN’s role in RDAP can be found here.

Installation

Add the library to your Cargo.toml: cargo add icann-rdap-client

Also, add the commons library: cargo add icann-rdap-common.

Both icann-rdap-common and icann-rdap-client can be compiled for WASM targets.

Usage

In RDAP, bootstrapping is the process of finding the authoritative RDAP server to query using the IANA RDAP bootstrap files. To make a query using bootstrapping:

use icann_rdap_client::*;
use std::str::FromStr;
use tokio::main;

#[tokio::main]
async fn main() -> Result<(), RdapClientError> {

    // create a query
    let query = QueryType::from_str("192.168.0.1")?;
    // or
    let query = QueryType::from_str("icann.org")?;

    // create a client (from icann-rdap-common)
    let config = ClientConfig::default();
    let client = create_client(&config)?;
    // ideally, keep store in same context as client
    let store = MemoryBootstrapStore::new();

    // issue the RDAP query
    let response =
        rdap_bootstrapped_request(
           &query,
           &client,
           &store,
           |reg| eprintln!("fetching {reg:?}")
    ).await?;

    Ok(())
}

To specify a base URL:

use icann_rdap_client::*;
use std::str::FromStr;
use tokio::main;

#[tokio::main]
async fn main() -> Result<(), RdapClientError> {

    // create a query
    let query = QueryType::from_str("192.168.0.1")?;
    // or
    let query = QueryType::from_str("icann.org")?;

    // create a client (from icann-rdap-common)
    let config = ClientConfig::default();
    let client = create_client(&config)?;

    // issue the RDAP query
    let base_url = "https://rdap-bootstrap.arin.net/bootstrap";
    let response = rdap_request(base_url, &query, &client).await?;

    Ok(())
}

Modules

• md
• query
• request

Structs

• ClientConfig
  Configures the HTTP client.
• MemoryBootstrapStore
  A bootstrap registry store backed by memory.
• ParsingErrorInfo
  Describes the error that occurs when parsing RDAP responses.

Enums

• QueryType
  Defines the various types of RDAP lookups and searches.
• RdapClientError
  Error returned by RDAP client functions and methods.

Functions

• create_client
  Creates an HTTP client using Reqwest. The Reqwest client holds its own connection pools, so in many uses cases creating only one client per process is necessary.
• rdap_bootstrapped_request
  Makes an RDAP request using bootstrapping.
• rdap_request
  Makes an RDAP request with a base URL.
• rdap_url_request
  Makes an RDAP request with a full RDAP URL.
