Trait diesel::query_source::Table

pub trait Table: QuerySource + AsQuery + Sized {
    type PrimaryKey: SelectableExpression<Self> + NonAggregate;
    type AllColumns: SelectableExpression<Self> + NonAggregate;
    fn primary_key(&self) -> Self::PrimaryKey;
    fn all_columns() -> Self::AllColumns;
}

A SQL database table. Types which implement this trait should have been generated by the table! macro.

Associated Types

The type returned by primary_key

type AllColumns: SelectableExpression<Self> + NonAggregate

The type returned by all_columns

Required Methods

fn primary_key(&self) -> Self::PrimaryKey
