technitium 0.4.0

# technitium

Typed async Rust client for the [Technitium DNS Server](https://technitium.com/dns/) HTTP API.

## Installation

```toml
[dependencies]
technitium = "0.1"
tokio = { version = "1", features = ["macros", "rt-multi-thread"] }
```

## Quick Start

```rust,no_run
use technitium::{Client, ZoneType};

#[tokio::main]
async fn main() -> Result<(), technitium::Error> {
    let client = Client::builder()
        .base_url("http://localhost:5380")
        .build()?;

    client.login("admin", "admin").await?;

    // Create a zone
    client.create_zone("example.com", ZoneType::Primary).await?;

    // List zones
    let zones = client.list_zones().await?;
    for zone in &zones {
        println!("{} ({:?})", zone.name, zone.zone_type);
    }

    Ok(())
}
```

## Error Handling

All errors are typed — match on variants without string parsing:

```rust,no_run
use technitium::{Client, Error};

# async fn example() {
let client = Client::builder()
    .base_url("http://localhost:5380")
    .build()
    .unwrap();

match client.login("admin", "wrong").await {
    Ok(()) => println!("logged in"),
    Err(Error::Authentication { message }) => eprintln!("bad creds: {message}"),
    Err(Error::TwoFactorRequired) => eprintln!("need TOTP"),
    Err(e) => eprintln!("other: {e}"),
}
# }
```
