Struct RowDatasetVersionRun 

pub struct RowDatasetVersionRun {
    pub span: U64Segment,
    pub version: u64,
}

A run of identical versions over a contiguous span of row positions.

Span is expressed as a U64Segment over row offsets (0..N within a fragment), not over row IDs. This keeps the encoding aligned with RowIdSequence order and enables zipped iteration without building a map.

Fields

span: U64Segment

version: u64

Implementations

impl RowDatasetVersionRun

pub fn len(&self) -> usize

Number of rows covered by this run.

pub fn is_empty(&self) -> bool

Whether this run covers no rows.

pub fn version(&self) -> u64

The version value of this run.

Trait Implementations

impl Clone for RowDatasetVersionRun

fn clone(&self) -> RowDatasetVersionRun

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RowDatasetVersionRun

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

Formats the value using the given formatter.

impl DeepSizeOf for RowDatasetVersionRun

fn deep_size_of_children(&self, context: &mut Context) -> usize

Returns an estimation of the heap-managed storage of this object. This does not include the size of the object itself.

fn deep_size_of(&self) -> usize

Returns an estimation of a total size of memory owned by the object, including heap-managed storage.

impl PartialEq for RowDatasetVersionRun

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