Trait ToSQL 

pub trait ToSQL<'a, 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.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
