Trait diesel::prelude::Table

pub trait Table: QuerySource + AsQuery + Sized {
    type PrimaryKey: SelectableExpression<Self> + ValidGrouping<()>;
    type AllColumns: SelectableExpression<Self> + ValidGrouping<()>;

    // Required methods
    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.

Required Associated Types

type PrimaryKey: SelectableExpression<Self> + ValidGrouping<()>

The type returned by primary_key

type AllColumns: SelectableExpression<Self> + ValidGrouping<()>

The type returned by all_columns

Required Methods

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

Returns the primary key of this table.

If the table has a composite primary key, this will be a tuple.

fn all_columns() -> Self::AllColumns

Returns a tuple of all columns belonging to this table.

Object Safety

This trait is not object safe.
