Struct TokenCache

pub struct TokenCache { /* private fields */ }

TokenCache provides the current OAuth2 token and a means to refresh it in a thread-safe way.

Implementations

impl TokenCache

pub fn new(auth: Authorization) -> Self

Make a new token cache, using the given Authorization as a source of tokens.

pub fn get_token(&self) -> Option<Arc<String>>

Get the current token, unless no cached token is set yet.

pub async fn update_token( &self, client: impl NoauthClient, old_token: Arc<String>, ) -> Result<Arc<String>, Error>

Forces an update to the token, for when it is detected that the token is expired.

To avoid double-updating the token in a race, requires the token which is being replaced. For the case where no token is currently present, use the empty string as the token.

pub fn set_access_token(&self, access_token: String)

Set the current short-lived token to a specific provided value. Normally it should not be necessary to call this function; the token should be obtained automatically using the refresh token.
