Struct InMemoryDns

pub struct InMemoryDns { /* private fields */ }

in-memory Dns that can be used as a simplistic cache, or wrapped in DnsOverwrite to indicate dns overwrites.

Implementations

impl InMemoryDns

pub fn new() -> InMemoryDns

Creates a new empty InMemoryDns instance.

pub fn insert( &mut self, name: &Domain, addresses: Vec<IpAddr>, ) -> &mut InMemoryDns

Inserts a domain to IP address mapping to the InMemoryDns.

Existing mappings will be overwritten.

pub fn insert_address<A>(&mut self, name: &Domain, addr: A) -> &mut InMemoryDns

where A: Into<IpAddr>,

Insert an IP address for a domain.

This method accepts any type that can be converted into an IpAddr, such as Ipv4Addr or Ipv6Addr.

pub fn insert_addresses<I>( &mut self, name: &Domain, addresses: I, ) -> &mut InMemoryDns

where I: IntoIterator, <I as IntoIterator>::Item: Into<IpAddr>,

Insert multiple IP addresses for a domain.

This method accepts any iterator which item type can be converted into an IpAddr, such as Ipv4Addr or Ipv6Addr.

pub fn extend( &mut self, overwrites: impl IntoIterator<Item = (Domain, Vec<IpAddr>)>, ) -> &mut InMemoryDns

Extend the InMemoryDns with the given mappings.

Existing mappings will be overwritten.

Trait Implementations

impl AsRef<InMemoryDns> for DnsOverwrite

fn as_ref(&self) -> &InMemoryDns

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for InMemoryDns

fn clone(&self) -> InMemoryDns

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InMemoryDns

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

Formats the value using the given formatter.

impl Default for InMemoryDns

fn default() -> InMemoryDns

Returns the “default value” for a type.

impl DnsResolver for InMemoryDns

type Error = DomainNotMappedErr

Error returned by the DnsResolver

async fn ipv4_lookup( &self, domain: Domain, ) -> Result<Vec<Ipv4Addr>, <InMemoryDns as DnsResolver>::Error>

Resolve the ‘A’ records accessible by this resolver for the given Domain into Ipv4Addresses.

async fn ipv6_lookup( &self, domain: Domain, ) -> Result<Vec<Ipv6Addr>, <InMemoryDns as DnsResolver>::Error>

Resolve the ‘AAAA’ records accessible by this resolver for the given Domain into Ipv6Addresses.

fn boxed(self) -> BoxDnsResolver

Box this resolver to allow for dynamic dispatch.

impl From<InMemoryDns> for DnsOverwrite

fn from(value: InMemoryDns) -> DnsOverwrite

Converts to this type from the input type.
