Trait ToSQL 

pub trait ToSQL<'a, V>
where
    V: SQLParam,
{
    // Required method
    fn to_sql(&self) -> SQL<'a, V>;

    // Provided method
    fn into_sql(self) -> SQL<'a, V>
       where Self: Sized { ... }
}

Trait for types that can be converted to SQL fragments.

The 'a lifetime ties any borrowed parameter values to the resulting SQL fragment, allowing zero-copy SQL construction when inputs are already borrowed.

Required Methods

fn to_sql(&self) -> SQL<'a, V>

Provided Methods

fn into_sql(self) -> SQL<'a, V>

where Self: Sized,

Consume self and return SQL without cloning. Default delegates to to_sql() (which clones). Types that own their SQL (like SQL and SQLExpr) override this to avoid the clone.
