Struct QueryEnd 

#[non_exhaustive]
pub struct QueryEnd {
    pub reason: i32,
}

Available on crate feature unstable only.

Final response frame for a successful query stream. Every successful stream returns exactly one QueryEnd after all item and watermark frames.

The resume cursor is the last Watermark.cursor received during the stream — either standalone or embedded on the last item. Clients have to track the latest watermark themselves anyway (to survive mid-stream disconnects and pre-QueryEnd errors), so QueryEnd carries no cursor of its own: reason is the only thing it adds on top of what the stream already delivered.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

reason: i32

Reason this response stopped.

Implementations

impl QueryEnd

pub const REASON_FIELD: &'static MessageField

impl QueryEnd

impl QueryEnd

pub const fn const_default() -> Self

impl QueryEnd

Sets reason to the provided enum value.

Trait Implementations

impl Clone for QueryEnd

fn clone(&self) -> QueryEnd

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryEnd

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

Formats the value using the given formatter.

impl Default for QueryEnd

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for QueryEnd

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for QueryEnd

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 Message for QueryEnd

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl MessageFields for QueryEnd

const FIELDS: &'static [&'static MessageField]

impl PartialEq for QueryEnd

fn eq(&self, other: &QueryEnd) -> 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 Serialize for QueryEnd

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for QueryEnd

impl Eq for QueryEnd

impl StructuralPartialEq for QueryEnd
