A Recursor builder

Implementations

impl RecursorBuilder

pub fn ns_cache_size(self, size: usize) -> Self

Sets the size of the list of cached name servers

pub fn record_cache_size(self, size: usize) -> Self

Sets the size of the list of cached records

pub fn recursion_limit(self, limit: Option<u8>) -> Self

Sets the maximum recursion depth for queries; set to None for unlimited recursion.

pub fn ns_recursion_limit(self, limit: Option<u8>) -> Self

Sets the maximum recursion depth for building NS pools; set to None for unlimited recursion.

pub fn dnssec_policy(self, dnssec_policy: DnssecPolicy) -> Self

Sets the DNSSEC policy

pub fn nameserver_filter<'a>( self, allow: impl Iterator<Item = &'a IpNet>, deny: impl Iterator<Item = &'a IpNet>, ) -> Self

Add networks that should not be queried during recursive resolution

pub fn avoid_local_udp_ports(self, ports: HashSet<u16>) -> Self

Sets local UDP ports that should be avoided when making outgoing queries

pub fn ttl_config(self, ttl_config: TtlConfig) -> Self

Sets the minimum and maximum TTL values for cached responses

pub fn case_randomization(self, case_randomization: bool) -> Self

Enable case randomization.

Sets whether to randomize the case of letters in query names, and require that responses preserve the case.

pub fn build( self, roots: impl Into<NameServerConfigGroup>, ) -> Result<Recursor, Error>

Construct a new recursor using the list of NameServerConfigs for the root node list

Panics

This will panic if the roots are empty.
