Enum Refusal 

#[non_exhaustive]
pub enum Refusal {
    CircuitOpen,
    BulkheadFull,
    RateLimited,
}

A call the SDK turned away itself, before anything was sent. It shares ErrorCode::ApiError or ErrorCode::RateLimit with the server’s own refusals and is told apart by carrying no HTTP status and one of these.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

CircuitOpen

The scope’s circuit breaker is open. See crate::resilience.

BulkheadFull

The scope already has as many calls in flight as its bulkhead allows.

RateLimited

The client’s own rate limiter has no token to spend.
