Trait Handler

pub trait Handler<Op, Exts>
where
    Op: OperationShape,
{
    type Future: Future<Output = Result<Op::Output, Op::Error>>;

    // Required method
    fn call(&mut self, input: Op::Input, exts: Exts) -> Self::Future;
}

A utility trait used to provide an even interface for all operation handlers.

See operation documentation for more info.
