<!-- cargo-rdme start -->

A library for working with [BIP329 labels](https://github.com/bitcoin/bips/blob/master/bip-0329.mediawiki).

- The main data structure is the [`Labels`](https://docs.rs/bip329/latest/bip329/struct.Labels.html) struct, which is a list of [`Label`](https://docs.rs/bip329/latest/bip329/enum.Label.html) structs.
- The [`Label`](https://docs.rs/bip329/latest/bip329/enum.Label.html) enum containing all the different types of labels.
- The [`Labels`](https://docs.rs/bip329/latest/bip329/struct.Labels.html) struct can be imported/exported to/from a JSONL file.
- Supports encryption and decryption using the [`encryption`](https://docs.rs/bip329/latest/bip329/encryption/) module.
- Supports the [`uniffi`](https://github.com/mozilla/uniffi-rs) feature, for easy integration with other languages.

#### Example Import:
```rust
use bip329::Labels;

let labels = Labels::try_from_file("tests/data/labels.jsonl").unwrap();
```

#### Example Export:
```rust
use bip329::Labels;

// Create a Labels struct
let labels = Labels::try_from_file("tests/data/labels.jsonl").unwrap();

// Create a JSONL string
let jsonl = labels.export().unwrap();
```

#### Example encryption:
```rust
use bip329::{Labels, encryption::EncryptedLabels};

let labels = Labels::try_from_file("tests/data/labels.jsonl").unwrap();
let encrypted = EncryptedLabels::encrypt(&labels, "passphrase").unwrap();

let encrypted = EncryptedLabels::read_from_file("tests/data/encrypted_labels.age").unwrap();
let decrypted = encrypted.decrypt("passphrase").unwrap();
assert_eq!(labels, decrypted);
```
