All Implemented Interfaces:

io.zenoh.query.IntoParameters
```
public final class Parameters
 implements IntoParameters
                    
```
Parameters of the Selector.
When in string form, the parameters should be encoded like the query section of a URL:
- parameters are separated by ;,
- the parameter name and value are separated by the first =,
- in the absence of =, the parameter value is considered to be the empty string,
- both name and value should use percent-encoding to escape characters,
- defining a value for the same parameter name twice is considered undefined behavior and an error result is returned.
