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.
