namecheap-client 0.1.1

//! Read-modify-write: fetch a domain's DNS records, add one, and write them back.
//!
//! `setHosts` replaces the entire record set, so the safe way to add or change a
//! single record is to read the current set with `getHosts`, modify it, and send
//! the whole thing back.
//!
//! ```sh
//! NAMECHEAP_API_USER=your-user \
//! NAMECHEAP_API_KEY=your-key \
//! NAMECHEAP_CLIENT_IP=your.whitelisted.ip \
//!   cargo run --example dns_update_record
//! ```
