resolution mix
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 →
- Concrete method100%A method on a value whose type is known exactly.
- Embedded method<1%Reached through an embedded type.
estimate
Estimated relative cost
Roughly 0.12× the estimated relative cost of fmt.Sprintf . Benchmarked at 1146 ns/op × 2,508 production calls, normalized so fmt.Sprintf = 1.0.
This is not dollars and not a verdict. Per-op time depends heavily on inputs (argument sizes, contention, patterns), the benchmark ran on a single machine (darwin/arm64 (Apple Silicon), go1.26.0), and static call counts are not runtime frequency. How this is estimated →
