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.
- Method value1%A method captured as a value, then called.
