Struct dropbox_sdk::oauth2::TokenCache

pub struct TokenCache { /* fields omitted */ }

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, client: impl NoauthClient) -> Result<Arc<String>>

Get the current token, or obtain one if no cached token is set yet.

Unless the token has not been obtained yet, this does not do any HTTP request.

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

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.
