Struct dns_protocol::Flags

#[repr(transparent)]
pub struct Flags(_);

The flags associated with a DNS message.

Implementations

impl Flags

pub const fn new() -> Self

Create a new, empty set of flags.

pub const fn standard_query() -> Self

Use the standard set of flags for a DNS query.

This is identical to new() but uses recursive querying.

pub fn qr(&self) -> MessageType

Get the query/response flag.

pub fn set_qr(&mut self, qr: MessageType) -> &mut Self

Set the message’s query/response flag.

pub fn opcode(&self) -> Opcode

Get the opcode.

pub fn set_opcode(&mut self, opcode: Opcode)

Set the opcode.

pub fn authoritative(&self) -> bool

Get whether this message is authoritative.

pub fn set_authoritative(&mut self, authoritative: bool) -> &mut Self

Set whether this message is authoritative.

pub fn truncated(&self) -> bool

Get whether this message is truncated.

pub fn set_truncated(&mut self, truncated: bool) -> &mut Self

Set whether this message is truncated.

pub fn recursive(&self) -> bool

Get whether this message is recursive.

pub fn set_recursive(&mut self, recursive: bool) -> &mut Self

Set whether this message is recursive.

pub fn recursion_available(&self) -> bool

Get whether recursion is available for this message.

pub fn set_recursion_available(&mut self, recursion_available: bool) -> &mut Self

Set whether recursion is available for this message.

pub fn response_code(&self) -> ResponseCode

Get the response code.

pub fn set_response_code(&mut self, response_code: ResponseCode) -> &mut Self

Set the response code.

pub fn raw(self) -> u16

Get the raw value of these flags.

Trait Implementations

impl Clone for Flags

fn clone(&self) -> Flags

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Flags

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

Formats the value using the given formatter.

impl Default for Flags

fn default() -> Flags

Returns the “default value” for a type.

impl Hash for Flags

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,

Feeds a slice of this type into the given Hasher.

impl Ord for Flags

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl PartialEq<Flags> for Flags

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<Flags> for Flags

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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