Trait ToSQL 

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

    // Provided method
    fn alias(&self, alias: &'static str) -> SQL<'a, V> { ... }
}

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 alias(&self, alias: &'static str) -> SQL<'a, V>
