Unused line / define defaults?

[behinger]

I didnt fully understand this line of code - do we need it?

It seems to be a stub to use the default values. params is not used though?

TopoPlots.jl/src/interpolators.jl

Line 29 in 2b7c9d2

params = Iterators.filter(((k, v),) -> !(v isa Nothing), Dict(:tol => ct.tol, :maxiter => ct.maxiter, :rescale => ct.rescale))

Context:

TopoPlots.jl/src/interpolators.jl

Lines 25 to 35 in 2b7c9d2
