Struct RollbackOutcome 

pub struct RollbackOutcome {
    pub deleted: u64,
    pub restored: u64,
    pub conflicts: u64,
    pub applied: bool,
    pub note: Option<String>,
}

What a sink did (or would do) for one dataset.

Fields

deleted: u64

Rows deleted (append: the run’s rows; upsert: keys the run created).

restored: u64

Rows restored to their before-image (upsert), or rows swapped back (overwrite).

conflicts: u64

Keys a later run changed since; without force these block the whole dataset.

applied: bool

Whether changes were applied. false for a dry run, or when conflicts blocked the rollback.

note: Option<String>

A human note (e.g. why nothing was applied).
