Expand description

Types created by the alias! macro that serve to distinguish between aliases implement this trait.

In order to be able to implement within diesel a lot of traits on what will represent the alias, we cannot use directly that new type within the query builder. Instead, we will use Alias<S>, where S: AliasSource.

This trait should never be implemented by an end-user directly.

Required Associated Types

The table the alias maps to

Required Associated Constants

The name of this alias in the query

Required Methods

Obtain the table from the source
