Struct LazyChromeFailover 

pub struct LazyChromeFailover { /* private fields */ }

Available on crate feature chrome only.

Lazy, lock-free, leak-free holder for a ChromeConnectionFailover.

Constructed lazily on first call to get_or_init, then reused across every subsequent setup_browser_configuration invocation. After init, access is a single atomic load — no parking, no awaits, no mutexes.

Reset (via with_chrome_connections) replaces the cell with a fresh empty one; the previous Arc<ChromeConnectionFailover> drops cleanly once the last in-flight reader releases it.

Implementations

impl LazyChromeFailover

pub fn get_or_init( &self, urls: &[String], max_retries: u32, ) -> &Arc<ChromeConnectionFailover>

Borrow the failover, lazily initializing it on first call. The closure runs exactly once for the lifetime of this cell.

pub fn mark_url_bad(&self, url: &str, cooldown_millis: u64)

Mark a URL as dead on the inner failover (no-op if the cell hasn’t been initialized yet, or the URL isn’t part of the failover list). Lock-free: a single atomic store on the matching slot.

pub fn last_connected_url(&self) -> Option<&str>

Borrowed URL of the most recently-successful endpoint, or None when the cell hasn’t initialized or no successful connect has happened yet. Lock-free: one atomic load + one slice lookup.

Trait Implementations

impl Clone for LazyChromeFailover

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LazyChromeFailover

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LazyChromeFailover

fn default() -> LazyChromeFailover

Returns the “default value” for a type.

impl PartialEq for LazyChromeFailover

fn eq(&self, _other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
