Trait postgres::types::BorrowToSql
pub trait BorrowToSql: Sealed {
// Required method
fn borrow_to_sql(&self) -> &dyn ToSql;
}Expand description
A trait used by clients to abstract over &dyn ToSql and T: ToSql.
This cannot be implemented outside of this crate.

fn borrow_to_sql(&self) -> &dyn ToSql
fn borrow_to_sql(&self) -> &dyn ToSql
Returns a reference to self as a ToSql trait object.

Implementors§
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.
