Struct BackfillResult 

pub struct BackfillResult {
    pub step_index: usize,
    pub matched: u64,
    pub inserted: u64,
    pub skipped: u64,
    pub conflicts: u64,
}

Per-step backfill count result.

Fields

step_index: usize

Zero-based index of the step within the migration’s step list.

matched: u64

Number of owner instances that matched the source predicate (the total candidate set, including those already having the destination).

inserted: u64

Number of instances that were actually backfilled (destination inserted).

Computed as the count of the guarded match (insert-if-absent inserts exactly the guarded set).

skipped: u64

Number of instances skipped because they already held the destination attribute (matched - inserted).

conflicts: u64

Number of instances with conflicting source values. Always 0 for the single-valued v1 CopyAttribute op; reserved for future multi-valued ops.
