RetryDnsHandle

rama::dns::client::hickory::resolver::net::xfer::retry_dns_handle

Struct RetryDnsHandle 

pub struct RetryDnsHandle<H> { /* private fields */ }
Available on crate features dns and hickory and std only.
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.

note Current value of this is not clear, it may be removed
