Struct StoreViewDeltaStats 

#[non_exhaustive]
pub struct StoreViewDeltaStats {
    pub checkpoint_rows: usize,
    pub delta_segments: usize,
    pub delta_inserted_rows: usize,
    pub delta_deleted_rows: usize,
    pub delta_mutations: usize,
    pub tombstone_ratio_bps: u16,
}

Benchmark-only delta shape for one published relationship-store view.

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.

checkpoint_rows: usize

Number of rows in the checkpoint store.

delta_segments: usize

Number of delta overlays retained by the view.

delta_inserted_rows: usize

Number of inserted rows in the current delta overlay.

delta_deleted_rows: usize

Number of checkpoint rows masked by delta tombstones.

delta_mutations: usize

Number of mutations represented by the current delta overlay.

tombstone_ratio_bps: u16

Deleted-row ratio in basis points over checkpoint plus inserted rows.

Trait Implementations

impl Clone for StoreViewDeltaStats

fn clone(&self) -> StoreViewDeltaStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StoreViewDeltaStats

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

Formats the value using the given formatter.

impl Default for StoreViewDeltaStats

fn default() -> StoreViewDeltaStats

Returns the “default value” for a type.

impl PartialEq for StoreViewDeltaStats

fn eq(&self, other: &StoreViewDeltaStats) -> 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.
