Persist

trait Persist[T] extends ShowT[T] with Unshow[T]

A convenience trait type class trait for persistence, that combines the ShowDecT and Unshow type classes. Most if not all final classes that inherit from this trait will require type class instances of ShowT and UnShowT to implement PersistDec's members. It is most important that these implicit parameter instances be specified as separate ShowT and UnShowT parameters. Do not combine them into a Persist parameter. There are no implicit instances for Int, Double, List etc in the PersistDec companion object, the Persist components for these standard types will be found in the ShowT and UnShow companion objects.

def fromExpr(expr: Expr): EMon[T]

Tries to return a value of the type from an RSON expression Expr that has been parsed from a String or text file. This method must be implemented by all instances.

def strT(obj: T): String

Provides the standard string representation for the object. Its called ShowT to indicate this is a type class method that acts upon an object rather than a method on the object being shown.

def syntaxDepthT(obj: T): Int

Simple values such as Int, String, Double have a syntax depth of one. A Tuple3[String, Int, Double] has a depth of 2. Not clear whether this should always be determined at compile time or if sometimes it should be determined at runtime.

def typeStr: String

The RSON type of T. This the only data that a ShowT instance requires, that can't be implemented through delegation to an object of type Show.
