Implementations

impl DnsRrKey

pub fn datatype(self) -> DnsDataType

Returns the data type associated with this resource record key.

This tells the caller which getter/setter method to use (e.g. get_addr for DnsDataType::InAddr, get_str for DnsDataType::Str or DnsDataType::Name).

pub fn record_type(self) -> DnsRecordType

Returns the DNS record type that this key belongs to.

For example, DnsRrKey::A_ADDR returns DnsRecordType::A.

Trait Implementations

impl Clone for DnsRrKey

fn clone(&self) -> DnsRrKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DnsRrKey

impl Debug for DnsRrKey

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

Formats the value using the given formatter.

impl Display for DnsRrKey

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

Formats the value using the given formatter.

impl Eq for DnsRrKey

impl From<DnsRrKey> for ares_dns_rr_key_t

fn from(val: DnsRrKey) -> Self

Converts to this type from the input type.

impl From<ares_dns_rr_key_t> for DnsRrKey

fn from(val: ares_dns_rr_key_t) -> Self

Converts to this type from the input type.

impl Hash for DnsRrKey

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 DnsRrKey

fn cmp(&self, other: &DnsRrKey) -> 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 PartialEq for DnsRrKey

fn eq(&self, other: &DnsRrKey) -> 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 DnsRrKey

fn partial_cmp(&self, other: &DnsRrKey) -> 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.
