Struct DnsRequestOptions

A set of options for expressing options to how requests should be treated

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

expects_multiple_responses: bool

👎Deprecated

When true, the underlying DNS protocols will not return on the first response received.

Setting this option will cause the underlying protocol to await the timeout, and then return all Responses.

use_edns: bool

When true, will add EDNS options to the request.

edns_set_dnssec_ok: bool

When true, sets the DO bit in the EDNS options

max_request_depth: usize

Specifies maximum request depth for DNSSEC validation.

recursion_desired: bool

set recursion desired (or not) for any requests

case_randomization: bool

Randomize case of query name, and check that the response matches, for spoofing resistance.

Trait Implementations

impl Clone for DnsRequestOptions

fn clone(&self) -> DnsRequestOptions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DnsRequestOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for DnsRequestOptions

fn default() -> DnsRequestOptions

Returns the “default value” for a type.

impl PartialEq for DnsRequestOptions

fn eq(&self, other: &DnsRequestOptions) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
