Trait QueryArgs

pub trait QueryArgs: Send + Sync {
    // Required method
    fn encode(&self, encoder: &mut Encoder<'_>) -> Result<(), Error>;
}

A tuple of query arguments.

This trait is implemented for tuples of sizes up to twelve. You can derive it for a structure in this case it’s treated as a named tuple (i.e. query should include named arguments rather than numeric ones).

Required Methods

fn encode(&self, encoder: &mut Encoder<'_>) -> Result<(), Error>
