Expand description

Builder for DnsResolver.

Implementations§

Source §

impl Builder

Source

pub fn with_system_defaults(self) -> Self

Makes the builder respect the host system’s DNS configuration.

We first try to read the system’s resolver from /etc/resolv.conf. This does not work at least on some Androids, therefore we fallback to a default config which uses Google’s 8.8.8.8 or 8.8.4.4.

Source

pub fn with_nameserver(self, addr: SocketAddr, protocol: DnsProtocol) -> Self

Adds a single nameserver.

Source

pub fn with_nameservers( self, nameservers: impl IntoIterator<Item = (SocketAddr, DnsProtocol)>, ) -> Self

Adds a list of nameservers.

Source

pub fn build(self) -> DnsResolver

Builds the DNS resolver.
