Struct AggregationMetadata 

pub struct AggregationMetadata {
    pub source_count: u32,
    pub excluded_count: u32,
    pub aggregation_method: String,
    pub performed_at: Option<Timestamp>,
    pub oldest_source: Option<Timestamp>,
    pub newest_source: Option<Timestamp>,
}

Aggregation metadata

Provides context about how an aggregation was performed. Useful for debugging and understanding data staleness.

Fields

source_count: u32

Number of source documents aggregated

excluded_count: u32

Number of sources excluded (e.g., non-operational nodes)

aggregation_method: String

Aggregation method used

performed_at: Option<Timestamp>

Timestamp when aggregation was performed

oldest_source: Option<Timestamp>

Oldest source document timestamp (for staleness detection)

newest_source: Option<Timestamp>

Newest source document timestamp

Trait Implementations

impl Clone for AggregationMetadata

fn clone(&self) -> AggregationMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AggregationMetadata

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

Formats the value using the given formatter.

impl Default for AggregationMetadata

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AggregationMetadata

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for AggregationMetadata

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 PartialEq for AggregationMetadata

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

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
