Struct CredentialsMemoryStorage

pub struct CredentialsMemoryStorage<Id, Secret>
where
    Id: Hash,
{ /* private fields */ }

Stores credentials in memory for authentication.

For simplicity, this storage does implement both CredentialsStorageService as well as CredentialsVerifierService.

Create and use a credential storage for authentication

let hasher = Argon2Hasher::default();
// Lets assume the user id is an email address and the user has a gooood password.
let creds = Credentials::new("admin@example.com", "admin_password".as_bytes())
    .hash_secret(&hasher)
    .unwrap();
let creds_to_verify = Credentials::new("admin@example.com", "admin_password".as_bytes().to_vec());
// In order to enable user verification we need to store a hashed version in our pre-defined
// memory storage.
let creds_storage = CredentialsMemoryStorage::from(vec![creds.clone()]);
assert_eq!(true, creds_storage.verify_credentials(&creds_to_verify, &hasher).await.unwrap());
let false_creds = Credentials::new("admin@example.com", "crazysecret".as_bytes())
    .hash_secret(&hasher).unwrap();
assert_eq!(false, creds_storage.verify_credentials(&false_creds, &hasher).await.unwrap());

Trait Implementations

impl<Id, Secret: Clone> Clone for CredentialsMemoryStorage<Id, Secret>

where Id: Hash + Clone,

fn clone(&self) -> CredentialsMemoryStorage<Id, Secret>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<Id, Secret> CredentialsStorageService<Id, Secret> for CredentialsMemoryStorage<Id, Secret>

where Id: Hash + Eq + Clone,

async fn store_credentials( &self, credentials: Credentials<Id, Secret>, ) -> Result<bool, Error>

Stores the credentials. Returns true on success, false if the Credentials::id already exists.

async fn remove_credentials( &self, credentials: Credentials<Id, Secret>, ) -> Result<bool, Error>

Removed the credentials. Returns true on success, false if the Credentials::id does NOT exists.

async fn update_credentials( &self, credentials: Credentials<Id, Secret>, ) -> Result<(), Error>

Updates the credentials.

impl<Id, Secret> CredentialsVerifierService<Id, Secret> for CredentialsMemoryStorage<Id, Vec<u8>>

where Id: Hash + Eq, Secret: Into<Vec<u8>> + Clone,

async fn verify_credentials<Hasher>( &self, credentials: &Credentials<Id, Secret>, hasher: &Hasher, ) -> Result<bool, Error>

where Hasher: SecretsHashingService,

Returns true if the given secret matches the one in your secret storage.

impl<Id, Secret> Default for CredentialsMemoryStorage<Id, Secret>

where Id: Hash,

fn default() -> Self

Returns the “default value” for a type.

impl<Id, Secret> From<Vec<Credentials<Id, Secret>>> for CredentialsMemoryStorage<Id, Secret>

where Id: Hash + Eq,

fn from(value: Vec<Credentials<Id, Secret>>) -> Self

Converts to this type from the input type.
