How each call resolves

How each call was attributed. Only resolved kinds, where the target function is known, count toward the ranking. Interface dispatch and unresolved receivers are reported separately and never guessed. Read the taxonomy →

  • Embedded method<1%Reached through an embedded type.
  • Interface method100%Called through an interface. The runtime target may differ.
