Source

pub trait TokenStorage: Send + Sync {
    // Required methods

    fn clear(&self) -> Result<(), StorageError>;
}

Expand description

Trait for persistent token storage.

Implement this trait to create custom storage backends for authentication tokens. The storage must be thread-safe (Send + Sync).

§Platform Examples

Desktop: Use FileTokenStorage to store tokens in the user’s config directory
iOS: Implement using Keychain Services
Android: Implement using EncryptedSharedPreferences

§Example Implementation

use edgefirst_client::{TokenStorage, StorageError};

struct KeychainStorage {
    service: String,
    account: String,
}

impl TokenStorage for KeychainStorage {
    fn store(&self, token: &str) -> Result<(), StorageError> {
        // Store in Keychain
        Ok(())
    }

    fn load(&self) -> Result<Option<String>, StorageError> {
        // Load from Keychain
        Ok(Some("token".to_string()))
    }

    fn clear(&self) -> Result<(), StorageError> {
        // Remove from Keychain
        Ok(())
    }
}
