Trait JoinArg 

pub trait JoinArg<'a, FromTable> {
    type JoinedTable;

    // Required method
    fn into_join_sql(self, join: Join) -> SQL<'a, PostgresValue<'a>>;
}

Trait for arguments accepted by .join() and related join methods.

Required Associated Types

type JoinedTable

Required Methods

fn into_join_sql(self, join: Join) -> SQL<'a, PostgresValue<'a>>

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types

impl<'a, U, C, T> JoinArg<'a, T> for (U, C)

where U: PostgresTable<'a>, C: ToSQL<'a, PostgresValue<'a>>,

Tuple (table, condition): explicit ON condition.

type JoinedTable = U

fn into_join_sql(self, join: Join) -> SQL<'a, PostgresValue<'a>>

Implementors

impl<'a, U, T> JoinArg<'a, T> for U

where U: PostgresTable<'a> + Joinable<T>, T: SQLTableInfo + Default,

Bare table: derives the ON condition from Joinable::fk_columns().

type JoinedTable = U
