Expand description

A single event emitted while explaining a merge.

Variants§

§

FastPath

The merge returned from a root-level fast path.

Fields

§reason: MergeFastPath
§

StructuralMergeStarted

The structural merge fast path started.

§

ReusedSubtree

An existing subtree CID was reused without rewriting that subtree.

Fields

§cid: Cid
§reason: MergeReuseReason
§

RewrittenNode

A new node was written by the structural merge path.

Fields

§cid: Cid
§level: u8
§entries: usize
§first_key: Option<Vec<u8>>
§last_key: Option<Vec<u8>>
§

ResolverCalled

The caller-provided resolver was invoked for a conflict.

Fields

§stage: MergeTraceStage
§key: Vec<u8>
§resolution: MergeResolutionKind
§

Fallback

A fast path could not finish and merge fell back to a broader path.

Fields

§reason: MergeFallbackReason
§

DiffTraversal

Counters from the structural diff traversal used by the diff/batch path.

§

BatchMerge

The diff/batch merge path applied right-side changes to left.

Fields

§right_changes: usize
§mutations: usize
§append_only: bool
