See the README for the examples directory for details.
Dict Basics.Int (String -> Result String x)
An Elm Dict mapping version numbers to decoder functions
encodeVersionedJson : Basics.Int -> x -> (x -> String) -> String
Convert a value to a versioned Json string
decodeVersionedJson : String -> ConverterDict x -> Result String x
Decode a string saved by encodeVersionedJson
with the relavant converter function
from a dictionary you provide.
If the string is not as encoded by encodeVersionedJson
, use the converter function
for version 0.
