Struct BatchOutcome 

pub struct BatchOutcome {
    pub nodes_inserted: usize,
    pub edges_inserted: usize,
    pub skipped: usize,
    pub replaced: usize,
    pub kept_view_owned: usize,
    pub row_errors: Vec<(usize, String)>,
}

What one committed batch did.

BatchBuilder::commit returns the first two fields as a tuple; the rest exist for OnConflict and are always zero / empty without it.

Fields

nodes_inserted: usize

Node records actually written.

edges_inserted: usize

Edge records actually written. A duplicate edge is a silent no-op under every policy — adjacency is a set — and is not counted.

skipped: usize

Rows whose key was taken and whose policy was OnConflict::Skip.

replaced: usize

Rows whose key was taken and whose policy was OnConflict::Replace.

kept_view_owned: usize

View-owned properties an OnConflict::Replace row kept although the caller did not supply them — counted per field, so one row that keeps two contributes two.

This is the one respect in which Replace does not make a node’s props exactly the supplied ones (see OnConflict::Replace). Those rows still count in replaced and still raise no row_errors, because nothing went wrong: a view’s property is not the caller’s to supply or to remove. A mirror rebuild that needs its copy to be byte-exact reads this to learn that the store kept fields its frame did not describe.

row_errors: Vec<(usize, String)>

(row, why) for rows an OnConflict::Replace refused. row counts node-insert ops in this batch from zero, which for a caller that queues its nodes in order is the index of the offending node. The rest of the frame still commits; the refused row changes nothing.
