Struct RetryEngine 

pub struct RetryEngine { /* private fields */ }

Smart retry engine with stealth-first escalation and browser rotation.

All internal state is lock-free: atomics for counters, DashMap-backed FailureTracker, and plain local sets for down-backend tracking (the engine is !Sync by design – a single owner drives the retry loop).

Implementations

impl RetryEngine

pub fn new(opts: RetryOptions) -> Self

Create a new retry engine from the given options.

pub fn stealth_level(&self) -> u32

Current stealth level (0 = auto, 1-3 = explicit tiers).

pub async fn execute<T, F, Fut>( &mut self, make_future: F, ctx: &mut RetryContext, ) -> Result<T, SpiderError>

where F: FnMut() -> Fut, Fut: Future<Output = Result<T, SpiderError>>,

Execute an action with stealth-first retry across browsers and stealth levels.
