Struct EmbedJunction 

pub struct EmbedJunction {
    pub schema: String,
    pub table: String,
    pub parent_columns: Vec<(String, String)>,
    pub child_columns: Vec<(String, String)>,
}

The table a many-to-many relationship is joined through.

Fields

schema: String

Schema holding the junction table.

table: String

The junction table’s name.

parent_columns: Vec<(String, String)>

(parent column, junction column) for each column the parent joins on.

Usually one. A junction may be keyed over several columns on each side – touched_files joins files(project_id, filename) to users_tasks(user_id, task_id) – and joining on the first of them alone would relate rows that are not related.

child_columns: Vec<(String, String)>

(junction column, child column) for each column the child joins on.
