Struct RetryingChunkGet 

Source 
pub struct RetryingChunkGet<G, S> { /* private fields */ }
Expand description

ChunkGet decorator that retries transient get failures with capped exponential backoff and jitter, sleeping through an injected Sleeper.

Retries on any error since the inner error type is opaque here; a genuinely unretrievable chunk still fails, but only after the attempt budget is spent. put and has delegate to the inner store untouched. Clone is cheap when G and S are.
