Enum QueryEvent 

#[non_exhaustive]
pub enum QueryEvent<'a> {
    Answer(Ref<'a>),
    Truncated,
}

Events delivered from Endpoint::handle() to a Query.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Answer(Ref<'a>)

A matching answer record arrived.

Truncated

Query received a truncated response (TC bit). Caller should hold off cancelling this query — more KAS suppression follows.

Implementations

impl<'a> QueryEvent<'a>

pub const fn is_answer(&self) -> bool

Returns true if this value is of type Answer. Returns false otherwise

pub const fn is_truncated(&self) -> bool

Returns true if this value is of type Truncated. Returns false otherwise

impl<'a> QueryEvent<'a>

pub fn unwrap_answer(self) -> Ref<'a>

Unwraps this value to the QueryEvent::Answer variant. Panics if this value is of any other type.

pub fn unwrap_answer_ref(&self) -> &Ref<'a>

Unwraps this reference to the QueryEvent::Answer variant. Panics if this value is of any other type.

pub fn unwrap_truncated(self)

Unwraps this value to the QueryEvent::Truncated variant. Panics if this value is of any other type.

pub fn unwrap_truncated_ref(&self)

Unwraps this reference to the QueryEvent::Truncated variant. Panics if this value is of any other type.

impl<'a> QueryEvent<'a>

pub fn try_unwrap_answer(self) -> Result<Ref<'a>, TryUnwrapError<Self>>

Attempts to unwrap this value to the QueryEvent::Answer variant. Returns a [TryUnwrapError] with the original value if this value is of any other type.

pub fn try_unwrap_answer_ref(&self) -> Result<&Ref<'a>, TryUnwrapError<&Self>>

Attempts to unwrap this reference to the QueryEvent::Answer variant. Returns a [TryUnwrapError] with the original value if this value is of any other type.

pub fn try_unwrap_truncated(self) -> Result<(), TryUnwrapError<Self>>

Attempts to unwrap this value to the QueryEvent::Truncated variant. Returns a [TryUnwrapError] with the original value if this value is of any other type.

pub fn try_unwrap_truncated_ref(&self) -> Result<(), TryUnwrapError<&Self>>

Attempts to unwrap this reference to the QueryEvent::Truncated variant. Returns a [TryUnwrapError] with the original value if this value is of any other type.

Trait Implementations

impl<'a> Clone for QueryEvent<'a>

fn clone(&self) -> QueryEvent<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for QueryEvent<'a>

impl<'a> Debug for QueryEvent<'a>

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

Formats the value using the given formatter.
