Operation code for queries, updates, and responses

RFC 1035, DOMAIN NAMES - IMPLEMENTATION AND SPECIFICATION, November 1987

OPCODE          A four bit field that specifies kind of query in this
                message.  This value is set by the originator of a query
                and copied into the response.  The values are:

                0               a standard query (QUERY)

                1               an inverse query (IQUERY)

                2               a server status request (STATUS)

                3-15            reserved for future use

Methods

impl OpCode[src]

Convert from u8 to OpCode

use std::convert::From;
use trust_dns_proto::op::op_code::OpCode;

let var: OpCode = OpCode::from_u8(0).unwrap();
assert_eq!(OpCode::Query, var);

pub fn from_u8(value: u8) -> ProtoResult<Self>[src]

Decodes the binary value of the OpCode
