Struct TokenRefresher 

pub struct TokenRefresher { /* private fields */ }

Single-flight token refresher keyed by an arbitrary string (typically location ID or company ID). Ensures that concurrent callers for the same key share one refresh request, preventing refresh-token rotation conflicts.

Implementations

impl TokenRefresher

pub fn new() -> Self

pub async fn ensure_valid<F, Fut>( &self, key: &str, token: &mut TokenData, refresh: F, ) -> Result<()>

where F: FnOnce() -> Fut + Send, Fut: Future<Output = Result<TokenData>> + Send,

Acquire a per-key lock and refresh the token if expired.

key is the location/company identifier. token is the current TokenData (will be updated in place if refreshed). refresh is an async callable that performs the refresh and returns a new TokenData.
