Struct Hinfo

pub struct Hinfo { /* private fields */ }

Hinfo record data.

Hinfo records are used to acquire general information about a host, specifically the CPU type and operating system type.

The Hinfo type is defined in RFC 1035, section 3.3.2.

Implementations

impl Hinfo

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

Creates a new Hinfo record data from the components.

pub fn cpu(&self) -> &CharStr

The CPU type of the host.

pub fn os(&self) -> &CharStr

The operating system type of the host.

Trait Implementations

impl Clone for Hinfo

fn clone(&self) -> Hinfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Compose for Hinfo

fn compose_len(&self) -> usize

Returns the number of bytes this value will need without compression.

fn compose<B: BufMut>(&self, buf: &mut B)

Appends the uncompressed representation of this value to buf.

impl Compress for Hinfo

fn compress(&self, buf: &mut Compressor) -> Result<(), ShortBuf>

Appends the wire-format representation of the value to buf.

impl Debug for Hinfo

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

Formats the value using the given formatter.

impl Display for Hinfo

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

Formats the value using the given formatter.

impl<N> From<Hinfo> for AllRecordData<N>

fn from(value: Hinfo) -> Self

Converts to this type from the input type.

impl<N> From<Hinfo> for MasterRecordData<N>

fn from(value: Hinfo) -> Self

Converts to this type from the input type.

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 Ord for Hinfo

fn cmp(&self, other: &Hinfo) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl Parse for Hinfo

type Err = ShortBuf

The type of an error returned when parsing fails.

fn parse(parser: &mut Parser) -> Result<Self, Self::Err>

Extracts a value from the beginning of parser.

fn skip(parser: &mut Parser) -> Result<(), Self::Err>

Skips over a value of this type at the beginning of parser.

impl ParseAll for Hinfo

type Err = ParseAllError

The type returned when parsing fails.

fn parse_all(parser: &mut Parser, len: usize) -> Result<Self, Self::Err>

Parses a value len bytes long from the beginning of the parser.

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 PartialOrd for Hinfo

fn partial_cmp(&self, other: &Hinfo) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl RtypeRecordData for Hinfo

const RTYPE: Rtype = Rtype::Hinfo

The record type of a value of this type.

impl Scan for Hinfo

fn scan<C: CharSource>(scanner: &mut Scanner<C>) -> Result<Self, ScanError>

Scans a value from a master file.
