Struct CommitRange 

pub struct CommitRange { /* private fields */ }

A contiguous range of Delta commits, holding resolved [start_version, end_version] bounds plus the materialized commit-file pointers in commit_files.

The pointer order matches the CommitOrdering requested at build time (ascending by default; reversed if CommitOrdering::DescendingOrder). Reading the underlying actions is lazy via CommitRange::commits.

Implementations

impl CommitRange

pub fn builder_for( table_root: impl AsRef<str>, start_version: Version, ) -> CommitRangeBuilder

Begin building a CommitRange rooted at table_root, starting at start_version.

pub fn builder_from( snapshot: SnapshotRef, start_version: Version, ) -> CommitRangeBuilder

Begin building a CommitRange derived from an existing snapshot, starting at start_version.

The snapshot’s table root anchors the range, and the snapshot’s LogSegment is reused to enumerate commits, avoiding an extra delta-log listing.

pub fn start_version(&self) -> Version

First version (inclusive) in the range.

pub fn end_version(&self) -> Version

Last version (inclusive) in the range.

pub fn table_root(&self) -> &Url

The table root URL this range was built from.

pub fn commits( &self, engine: Arc<dyn Engine>, start_snapshot: Option<SnapshotRef>, actions: &[DeltaAction], ) -> DeltaResult<impl Iterator<Item = DeltaResult<CommitAction>> + Send>

Iterator over the commits in the range, yielding one CommitAction per commit.

• engine: performs the per-commit JSON reads.
• start_snapshot: optional snapshot whose version anchors the range and seeds protocol/metadata validation; None validates from the commits alone.
• actions: the action kinds to project into each commit’s read schema.

Actions are returned raw, exactly as recorded in the commit JSON; no column-mapping translation is applied.

This is operation-agnostic: requesting DeltaAction::Cdc returns the raw cdc action records and does NOT impose change-data-feed support (Operation::Cdf). It does not materialize a change data feed.

Returns Err if actions is empty or contains duplicate kinds, or if start_snapshot belongs to a different table, its version does not match the range anchor, or its table does not support scanning.
