class FromJSONWithContext ctx a | a -> ctx where Source #
Similar to FromJSON, except the parser can also source data with which
to construct a from a context ctx.
This can be useful if the a value contains some data that is not from the
current piece of JSON (the Value). For example, some data from higher
up in the overall JSON graph, or from some system context.
