Struct trust_dns_proto::xfer::retry_dns_handle::RetryDnsHandle
source · [−]pub struct RetryDnsHandle<H> where
H: DnsHandle + Unpin + Send,
H::Error: RetryableError, { /* private fields */ }
Expand description
Can be used to reattempt queries if they fail
Note: this does not reattempt queries that fail with a negative response.
For example, if a query gets a NODATA
response from a name server, the
query will not be retried. It only reattempts queries that effectively
failed to get a response, such as queries that resulted in IO or timeout
errors.
Whether an error is retryable by the RetryDnsHandle
is determined by the
RetryableError
trait.
note Current value of this is not clear, it may be removed
