Implementors§

source§

impl BorrowToSql for &(dyn ToSql + Sync)

In async contexts it is sometimes necessary to have the additional Sync requirement on parameters for queries since this enables the resulting Futures to be Send, hence usable in, e.g., tokio::spawn. This instance is provided for those cases.

impl BorrowToSql for &dyn ToSql

impl<T> BorrowToSql for T
where T: ToSql,
