Type Alias TranslationFn 

pub type TranslationFn = Box<dyn Fn(&str, ParameterBinding<ExpressionTranslation>) -> Result<SQLExpression> + Send + Sync>;

Type alias for translation functions.

Translation functions take:

• name: The name the function was called with (useful for operators that map to SQL)
• bindings: The bound parameter values (already translated to SQL)

And return the translated SQL expression.
