Capturing the types of the values, from the type of a Named Tuple

Not sure this answers the question, but maybe fieldtypes does what you’re looking for:

julia> nt = (a = 1.0, b = 1, c = "A")
(a = 1.0, b = 1, c = "A")

julia> T = typeof(nt)
@NamedTuple{a::Float64, b::Int64, c::String}

julia> fieldtypes(T)
(Float64, Int64, String)
