Struct YahooAuthManager 

pub struct YahooAuthManager { /* private fields */ }

Manages Yahoo Finance authentication (cookies and crumb).

Yahoo Finance requires a valid crumb token for API requests. This manager handles obtaining and refreshing the crumb automatically.

Implementations

impl YahooAuthManager

pub fn new(proxy: Option<String>, cookie_jar: Arc<Jar>) -> Self

Create a new YahooAuthManager.

Arguments

• proxy - Optional proxy URL for authentication requests
• cookie_jar - Shared cookie jar for storing session cookies

pub async fn refresh(&self) -> Result<(), YahooError>

Force refresh the authentication credentials.

pub async fn get_or_refresh(&self) -> Result<(Arc<Jar>, String), YahooError>

Get the current crumb, refreshing if necessary.

Returns a tuple of (cookie_jar, crumb) for use in API requests.

pub async fn crumb(&self) -> Option<String>

Get the current crumb without refreshing.

pub async fn switch_strategy_and_refresh(&self) -> Result<(), YahooError>

Force a strategy flip and refresh credentials. Used when Yahoo responds with generic 4xx indicating a potentially bad crumb, mirroring yfinance’s “retry with other cookie strategy” behavior.
