Trait Query 

pub trait Query: Sealed {
    type Result: 'static;
}

A typed IQv2 query. Result is the type that KafkaStreams::query returns per partition. This trait is sealed, so only the in-crate query types implement it.

Required Associated Types

type Result: 'static

What a successful QueryResult carries.

Dyn Compatibility

This trait is dyn compatible.

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