Talking about loggers and ZAP (interesting idea to accommodate API to the
JSON)
The following code gets 40ns/op
type FieldType uint8
type Field struct {
Key string
Type FieldType
Integer int64
String string
Interface interface{}
}
const (
// UnknownType is the default field type. Attempting to add it to an
encoder will panic.
UnknownType FieldType = iota
// Int64Type indicates that the field carries an int64.
Uint64Type
)
func Uint64(key string, val uint64) Field {
return Field{Key: key, Type: Uint64Type, Integer: int64(val)}
}
func handleFields(s string, fields ...Field) {
}
func BenchmarkZapApi(b *testing.B) {
b.ResetTimer()
for i := 0; i < b.N; i++ {
handleFields("Hello ",
Uint64("world", 0),
Uint64("world", 1),
Uint64("world", 2),
)
}
b.StopTimer()
}
