Slime in Fermented Pickle brine

I have pickles that have been fermenting for 3 weeks now, which in my experience is the ideal length of time. When I checked on them, there is mucousy slime in the brine. There’s no unpleasant smell, and the pickles are crunchy and taste like pickles. There is some yeast on the top of the brine, but this is something I’ve seen fairly frequently.

Can anyone identify this slime, and confirm if these pickles are safe to eat?
