The wallet-core crate provides the business logic for a digital identity wallet, handling credential storage, selection, and presentation.

Installation

[dependencies]
baseid-wallet-core = "0.1.0-alpha.1"

Create a Wallet

use baseid_wallet_core::store::InMemoryStore;
use baseid_wallet_core::wallet::Wallet;

let store = InMemoryStore::new();
let wallet = Wallet::new(store, "did:key:z6MkHolder...".into());

Store a Credential

wallet.store_credential("my-degree", jwt_bytes)?;

List Credentials

let credentials = wallet.list_credentials()?;
for (id, _cred) in &credentials {
    println!("Stored: {id}");
}

Match Against a Request

let matches = wallet.match_credentials(&presentation_request)?;
// Returns credentials that satisfy the verifier's requirements

Storage Backends

Backend	Use Case
InMemoryStore	Testing and development
Custom Store impl	Production (SQLite, filesystem, secure enclave)

Implement the Store trait to create a custom backend:

pub trait Store {
    fn put(&mut self, id: &str, data: &[u8]) -> Result<()>;
    fn get(&self, id: &str) -> Result<Option<Vec<u8>>>;
    fn list(&self) -> Result<Vec<String>>;
    fn delete(&mut self, id: &str) -> Result<()>;
}
