Enum ConflictAction 

pub enum ConflictAction {
    Nothing,
    Replace(Vec<usize>),
    Update {
        columns: Vec<usize>,
        plan: Box<Plan>,
    },
}

What happens to a row whose key the table already holds.

Variants

Nothing

The row is dropped.

Replace(Vec<usize>)

The held row takes the new row’s values in these columns.

Update

The held row takes the values the plan works out in these columns. The plan reads the held rows as the table and the new rows as QualifiedName::excluded, one of each per row it answers, and after a value for each column answers whether the row is updated at all.

Fields

columns: Vec<usize>

The columns that are set, by place in the table.

plan: Box<Plan>

The query that works the values out.
