Struct SimpleTarget 

pub struct SimpleTarget {
    pub tables: HashMap<String, Vec<Vec<SqliteValue>>>,
}

A simple in-memory “database” for testing changeset application.

Maps table_name -> Vec<row> where each row is Vec<SqliteValue>. This is intentionally minimal; the real apply engine would operate on the B-tree layer.

Fields

tables: HashMap<String, Vec<Vec<SqliteValue>>>
