Expand description

The load method

This trait should not be relied on directly by most apps. Its behavior is provided by RunQueryDsl. However, you may need a where clause on this trait to call load from generic code.

Required Associated Types§

source

type RowIter<'conn>: Iterator<Item = QueryResult<U>> where Conn: 'conn

Return type of LoadQuery::internal_load

Required Methods§

source

fn internal_load(self, conn: &mut Conn) -> QueryResult<Self::RowIter<'_>>

Available on crate feature i-implement-a-third-party-backend-and-opt-into-breaking-changes only.
