SelectTopNodes returns a set of the top maxNodes nodes in a graph.

SetLabel sets the specified key to the specified value for all samples in the profile.

ShowFrom drops all stack frames above the highest matching frame and returns whether a match was found. If showFrom is nil it returns false and does n

Stacks returns a StackSet for the profile in rpt.

StringList is similar to String but allows multiple values for a single flag

Symbolize symbolizes profile p by parsing data returned by a symbolz handler. syms receives the symbolz query (hex addresses separated by '+') and ret
