This PR appends the TableRequest protocol to the requirements of the DerivableRequest protocol.
This enhances the expressivity of DerivableRequest and associations:
Constrained extensions to DerivableRequest can now use
filter(key:)
,filter(keys:)
,orderByPrimaryKey()
, etcAssociations and constrained extensions to DerivableRequest can now use the full-text methods
matching(_:)
.The inspiration for this change comes from https://github.com/openbitapp/GRDB.swift. Thank you @robcas3!
Strictly speaking, this PR introduces breaking changes to both the experimental protocols Association and DerivableRequest:
Association now requires that its origin and destination associated types conform to the TableRecord protocol.
DerivableRequest now requires TableRequest conformance.
Those breaking changes should be harmess: it is highly unlikely any GRDB user defines custom types based on those protocols.
