Trait Function 

pub trait Function: Code {
    type Args: Encode;
    type Output: Decode + IntoValue;
}

Trait that ties function code, arguments and output together.

Users are free to implement their own functions – be that custom Modbus functions or alternate standard function implementations. In the latter case, consider making a pull request.

Required Associated Types

type Args: Encode

Function arguments type.

It must be encodable to get sent in the request.

type Output: Decode + IntoValue

Function output type.

It must be decodable from the response.

Dyn Compatibility

This trait is not dyn compatible.

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