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

impl HINFO

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

Creates a new HINFO record data.

Arguments

• cpu - A character-string which specifies the CPU type.
• os - A character-string which specifies the operating system type.

Return value

The new HINFO record data.

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 character-string which specifies the CPU type.
• os - A character-string which specifies the operating system type.

Return value

The new HINFO record data.

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

A character-string which specifies the CPU type.

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

A character-string which specifies the operating system type.

Trait Implementations

impl<'r> BinDecodable<'r> for HINFO

fn read(decoder: &mut BinDecoder<'r>) -> Result<Self, ProtoError>

Read the type from the stream

fn from_bytes(bytes: &'r [u8]) -> Result<Self, ProtoError>

Returns the object in binary form

impl BinEncodable for HINFO

fn emit(&self, encoder: &mut BinEncoder<'_>) -> Result<(), ProtoError>

Write the type to the stream

fn to_bytes(&self) -> Result<Vec<u8>, ProtoError>

Returns the object in binary form

impl Clone for HINFO

fn clone(&self) -> HINFO

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HINFO

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for HINFO

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for HINFO

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

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Hash for HINFO

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for HINFO

fn eq(&self, other: &HINFO) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl RecordData for HINFO

fn try_from_rdata(data: RData) -> Result<Self, RData>

Attempts to convert to this RecordData from the RData type, if it is not the correct type the original is returned

fn try_borrow(data: &RData) -> Option<&Self>

Attempts to borrow this RecordData from the RData type, if it is not the correct type the original is returned

fn record_type(&self) -> RecordType

Get the associated RecordType for the RecordData

fn into_rdata(self) -> RData

Converts this RecordData into generic RecordData

fn is_update(&self) -> bool

RDLENGTH = 0

impl Serialize for HINFO

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for HINFO
