Enum KeyColumnSource 

pub enum KeyColumnSource {
    Declared,
}

Which column key_uniqueness may measure, as recorded in a report’s metric semantics.

Only the current definition has a value. Through 0.12, with no column declared, the first column whose name had an id, key or pk word was the key, so a foreign key listed first was scored as the table key and column order moved the score; those releases recorded no definition.

Variants

Declared

The first identifier_columns entry the source has. With none declared there is no key component.
