Struct StoreSnapshot 

pub struct StoreSnapshot {
    pub timestamp: u64,
    pub metrics: StoreMetrics,
    pub tier_distribution: [u64; 4],
    pub byte_distribution: [u64; 4],
}

A point-in-time snapshot of store state for serialization and export.

Captures the metrics, tier distribution (block counts), and byte distribution at a single instant.

Fields

timestamp: u64

Monotonic tick at which the snapshot was taken.

metrics: StoreMetrics

Aggregate metrics at snapshot time.

tier_distribution: [u64; 4]

Block count per tier: [tier0, tier1, tier2, tier3].

byte_distribution: [u64; 4]

Byte count per tier: [tier0, tier1, tier2, tier3].

Implementations

impl StoreSnapshot

pub fn to_bytes(&self) -> Vec<u8>

Serialize to a simple key=value text format.

Each line is key=value\n. Numeric values are printed in decimal. This format is intentionally trivial to parse so that external tools (dashboards, log aggregators) can ingest it without pulling in a JSON library.

Trait Implementations

impl Clone for StoreSnapshot

fn clone(&self) -> StoreSnapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StoreSnapshot

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

Formats the value using the given formatter.
