Struct BrowserSelector 

pub struct BrowserSelector { /* private fields */ }

Picks the next browser in rotation based on per-domain failure history.

Follows the server’s hints.rs logic:

1. Try current browser until ROTATE_AFTER_FAILURES consecutive failures.
2. Then move to the next browser in BROWSER_ROTATION order.
3. Skip browsers that have also exceeded the failure threshold.

Implementations

impl BrowserSelector

pub fn new(tracker: FailureTracker) -> Self

Create a new selector backed by the given failure tracker.

pub fn failure_tracker(&self) -> &FailureTracker

Borrow the underlying failure tracker.

pub fn should_rotate(&self, domain: &str, current_browser: &str) -> bool

Check if the current browser should be rotated for a domain.

Returns true when the failure count for (domain, current_browser) meets or exceeds ROTATE_AFTER_FAILURES.

pub fn next_browser( &self, domain: &str, current_browser: &str, ) -> Option<&'static str>

Pick the next browser to try after current_browser has failed.

Walks BROWSER_ROTATION starting from the position after current_browser, wrapping around, and returns the first candidate that has not exceeded the failure threshold for domain.

Returns None if every browser in the rotation has been exhausted.

pub fn choose_browser<'a>(&self, domain: &str, fallback: &'a str) -> &'a str

where 'static: 'a,

Choose the best browser for a domain (mirrors hints.rs choose_browser_for_domain).

Returns the first browser in BROWSER_ROTATION that has not exceeded the failure threshold. Falls back to fallback if every browser is exhausted.
