[julia-users] Method fieldnames not defined

['Antoine Messager' via julia-users]

Hi,

I would like to find the field of SolverResults{Float64}. So according to 
the manual <http://julia.readthedocs.org/en/latest/manual/types/>, I just 
need to use the method fieldnames but unfortunately it is not defined. 
What can I do?

Thank you,
Antoine
