/** InputCaches for IvyConfiguration, ModuleSettings, and UpdateConfiguration
|
|
* The InputCaches for a basic data structure is built in two parts.
|
|
* Given the data structure:
|
|
* Data[A,B,C, ...]
|
|
* 1) Define a conversion from Data to the HList A :+: B :+: C :+: ... :+: HNil,
|
|
* excluding any members that should not be considered for caching
|
|
* 2) In theory, 1) would be enough and wrapHL would generate InputCache[Data] as long
|
|
* as all of InputCache[A], InputCache[B], ... exist. However, if any of these child
|
|
* InputCaches are constructed using wrapHL, you get a diverging implicit error. (I
|
|
* believe scalac is generating this error as specified, but that the implicits would
|
|
* be valid and not be infinite. This might take some effort to come up with a new rule
|
|
* that allows this)
|
|
* 3) So, we need to explicitly define the intermediate implicits. The general approach is:
|
|
* {{{
|
|
* object LN {
|
|
* ... Data => HList conversions ...
|
|
* }
|
|
* import LN._
|
|
* implicit dataCache: InputCache[Data] = wrapHL
|
|
*
|
|
* object L(N-1) ...
|
|
* }}}
|
|
* Each Data in LN only uses implicits from L(N-1).
|
|
* This way, higher levels (higher N) cannot see the HList conversions of subcomponents but can
|
|
* use the explicitly defined subcomponent implicits and there is no divergence.
|
|
* 4) Ideally, diverging implicits could be relaxed so that the ... = wrapIn lines could be removed.
