Methods

impl DNSClass

fn from_str(str: &str) -> DecodeResult<Self>

Convert from &str to DNSClass

use trust_dns::rr::dns_class::DNSClass;

let var: DNSClass = DNSClass::from_str("IN").unwrap();
assert_eq!(DNSClass::IN, var);

fn from_u16(value: u16) -> DecodeResult<Self>

Convert from u16 to DNSClass

use trust_dns::rr::dns_class::DNSClass;

let var = DNSClass::from_u16(1).unwrap();
assert_eq!(DNSClass::IN, var);

fn for_opt(value: u16) -> Self

Return the OPT version from value
