Struct MemoryStore 

pub struct MemoryStore { /* private fields */ }

In-memory credential store for testing.

This store keeps credentials in memory wrapped in SecretString (zeroize-on-drop, redacted Debug) for unit tests that don’t want to interact with the real OS keychain. The Debug impl shows the key set and a count, never the values, so accidentally logging a MemoryStore cannot leak plaintext.

Implementations

impl MemoryStore

pub fn new() -> Self

Create a new in-memory store.

pub fn with_credentials( credentials: impl IntoIterator<Item = (String, String)>, ) -> Self

Create a store pre-populated with credentials. Accepts plaintext (key, value) pairs for test ergonomics; the values are wrapped in SecretString before storage.

Trait Implementations

fn get(&self, key: &str) -> Result<Option<SecretString>>

Retrieve a stored credential.

fn delete(&self, key: &str) -> Result<()>

Delete a stored credential.

fn exists(&self, key: &str) -> bool

Check if a credential exists.

fn is_available(&self) -> bool

Check if this credential store is available and functional.

fn is_writable(&self) -> bool

impl Default for MemoryStore

fn default() -> MemoryStore
