Build a claim parser from named resolver functions

map_claim() produces a parser function by mapping impl fn formal names to resolver functions. Each resolver receives (claim, processed) and returns the value for its argument. Resolvers that only need claim can simply ignore processed.

Usage

map_claim(...)

Arguments

...

Named resolver functions. Names must match formals of the impl's fn. Each resolver has signature function(claim, processed).

Value

A function of class "map_claim" with signature function(claim, processed).

Details

Pass the result as claim_parser to baseline() or variant(). A variant without a claim_parser simply does not support state_null(); conclude() raises an error if a claim was stated but the active variant has none.
