where:

CPU             A <character-string> which specifies the CPU type.

OS              A <character-string> which specifies the operating
                system type.

Standard values for CPU and OS can be found in [RFC-1010].

HINFO records are used to acquire general information about a host.  The
main use is for protocols such as FTP that can use special procedures
when talking between machines or operating systems of the same type.

Implementations§

source§

impl HINFO

source

pub fn new(cpu: String, os: String) -> Self

Creates a new HINFO record data.

§Arguments
  • cpu - A which specifies the CPU type.
  • os - A which specifies the operating system type.
§Return value

The new HINFO record data.

source

pub fn from_bytes(cpu: Box<[u8]>, os: Box<[u8]>) -> Self

Creates a new HINFO record data from bytes. Allows creating binary record data.

§Arguments
  • cpu - A which specifies the CPU type.
  • os - A which specifies the operating system type.
§Return value

The new HINFO record data.

source

pub fn cpu(&self) -> &[u8]

A which specifies the CPU type.

source

pub fn os(&self) -> &[u8]

A which specifies the operating system type.

RFC 1033, DOMAIN OPERATIONS GUIDE, November 1987

HINFO (Host Info)

           <host>   [<ttl>] [<class>]   HINFO   <hardware>   <software>

   The HINFO record gives information about a particular host.  The data
   is two strings separated by whitespace.  The first string is a
   hardware description and the second is software.  The hardware is
   usually a manufacturer name followed by a dash and model designation.
   The software string is usually the name of the operating system.

   Official HINFO types can be found in the latest Assigned Numbers RFC,
   the latest of which is RFC-1010.  The Hardware type is called the
   Machine name and the Software type is called the System name.

   Some sample HINFO records:

           SRI-NIC.ARPA.           HINFO   DEC-2060 TOPS20
           UCBARPA.Berkeley.EDU.   HINFO   VAX-11/780 UNIX
