swift - Can an Associated Type be restricted by protocol conformance and a where-clause? -


i'm trying:

public protocol myprotocol {     associatedtype myarray: rangereplaceablecollectiontype myarray.generator.element == mytype     //... }

the protocol has property prototype of type [mytype]. decided generalize it. made associated type. can have conform best container type (rangereplaceablecollectiontype) syntax errors when added where clause. there (other) way specify not want generic container, restrict element type?
