Struct InMemoryTokenStore 

pub struct InMemoryTokenStore { /* private fields */ }

In-process token store. Useful for tests and as a shared cache across multiple strategy instances in the same process (e.g. a worker pool).

Internally stores the JSON-serialised form of the token wrapped in Zeroizing so the buffer is wiped on overwrite and on store drop. The SecretToken wrapped inside Token is ZeroizeOnDrop, so we deliberately don’t clone the in-memory Token value — round-tripping through serde gives us a fresh SecretToken on each load without violating that invariant.

Implementations

impl InMemoryTokenStore

pub fn new() -> Self

Create a new, empty in-memory token store.

Trait Implementations

impl Default for InMemoryTokenStore

fn default() -> Self

Returns the “default value” for a type.

impl TokenStore for InMemoryTokenStore

async fn load(&self) -> Option<Token>

Load the most recently saved token, or None if none has been stored (or the load failed). Errors are swallowed — the calling state machine falls back to fresh authentication when this returns None.

async fn save(&self, token: &Token)

Persist a token after a successful refresh or initial authentication. Best-effort — implementations should log on failure rather than returning an error.
