Trait diesel::query_builder::bind_collector::BindCollector [−][src]
pub trait BindCollector<DB: Backend> {
fn push_bound_value<T, U>(
&mut self,
bind: &U,
metadata_lookup: &DB::MetadataLookup
) -> QueryResult<()>
where
DB: HasSqlType<T>,
U: ToSql<T, DB>;
}Expand description
A type which manages serializing bind parameters during query construction.
The only reason you would ever need to interact with this trait is if you
are adding support for a new backend to Diesel. Plugins which are extending
the query builder will use AstPass::push_bind_param instead.
