pub struct Dns { /* private fields */ }
Expand description
Dns Resolver for all your lookup needs.
We try to keep this module as minimal as possible, and only expose the necessary functions to perform DNS lookups in function of Rama.
Please open an issue with clear goals and motivation if you need more functionality.
Implementations§
§impl Dns
impl Dns
pub fn insert_overwrite(
&mut self,
name: impl TryIntoName,
addresses: Vec<IpAddr>,
) -> Result<&mut Dns, OpaqueError>
pub fn insert_overwrite( &mut self, name: impl TryIntoName, addresses: Vec<IpAddr>, ) -> Result<&mut Dns, OpaqueError>
Inserts a domain to IP address mapping to overwrite the DNS lookup.
Existing mappings will be overwritten.
Note that this impacts both Self::ipv4_lookup
and Self::ipv6_lookup
,
meaning that no Ipv6 addresses will be returned for the domain.
pub fn extend_overwrites(
&mut self,
overwrites: HashMap<impl TryIntoName, Vec<IpAddr>>,
) -> Result<&mut Dns, OpaqueError>
pub fn extend_overwrites( &mut self, overwrites: HashMap<impl TryIntoName, Vec<IpAddr>>, ) -> Result<&mut Dns, OpaqueError>
Extend the overwrites with a new mapping.
Existing mappings will be overwritten.
See Self::insert_overwrite
for more information.
pub async fn ipv4_lookup(
&self,
name: impl TryIntoName,
) -> Result<impl Iterator<Item = Ipv4Addr>, OpaqueError>
pub async fn ipv4_lookup( &self, name: impl TryIntoName, ) -> Result<impl Iterator<Item = Ipv4Addr>, OpaqueError>
Performs a ‘A’ DNS record lookup.
pub async fn ipv4_lookup_trusted(
&self,
name: impl TryIntoName,
) -> Result<impl Iterator<Item = Ipv4Addr>, OpaqueError>
pub async fn ipv4_lookup_trusted( &self, name: impl TryIntoName, ) -> Result<impl Iterator<Item = Ipv4Addr>, OpaqueError>
Performs a ‘A’ DNS record lookup.
Same as Self::ipv4_lookup
but without consulting
the overwrites first.
pub async fn ipv6_lookup(
&self,
name: impl TryIntoName,
) -> Result<impl Iterator<Item = Ipv6Addr>, OpaqueError>
pub async fn ipv6_lookup( &self, name: impl TryIntoName, ) -> Result<impl Iterator<Item = Ipv6Addr>, OpaqueError>
Performs a ‘AAAA’ DNS record lookup.
pub async fn ipv6_lookup_trusted(
&self,
name: impl TryIntoName,
) -> Result<impl Iterator<Item = Ipv6Addr>, OpaqueError>
pub async fn ipv6_lookup_trusted( &self, name: impl TryIntoName, ) -> Result<impl Iterator<Item = Ipv6Addr>, OpaqueError>
Performs a ‘AAAA’ DNS record lookup.
Same as Self::ipv6_lookup
but without
consulting the overwrites first.
