[−][src]Trait embedded_nal::Dns

pub trait Dns {
    type Error: Debug;
    pub fn gethostbyname(
        &self, 
        hostname: &str, 
        addr_type: AddrType
    ) -> Result<IpAddr, Self::Error>;

    pub fn gethostbyaddr(
        &self, 
        addr: IpAddr
    ) -> Result<String<U256>, Self::Error>;
}

This trait is an extension trait for TcpStack and UdpStack for dns resolutions. It does not handle every DNS record type, but is meant as an embedded alternative to ToSocketAddrs, and is as such meant to resolve an ip address from a hostname, or a hostname from an ip address. This means that it only deals in host address records A (IPv4) and AAAA (IPv6).
