Struct RowChange 

pub struct RowChange {
    pub table: String,
    pub op: ChangeOp,
    pub columns: Vec<Option<String>>,
}

One row change extracted from a changeset.

columns holds the row’s column values in schema order. [walk] returns the row’s new values for INSERT/UPDATE and old values for DELETE, with unchanged UPDATE columns filled from the old side so primary keys and foreign keys stay available.

None means SQL NULL or a column absent from the changeset.

Fields

table: String

op: ChangeOp

columns: Vec<Option<String>>
