Functions ¶

func Durations ¶

func Durations(durs []time.Duration) uint64

Durations returns the accumulated identity of durs.

func Float64s ¶

func Float64s(f64s []float64) uint64

Float64s returns the accumulated identity of f64s.

func Int64s ¶

func Int64s(i64s []int64) uint64

Int64s returns the accumulated identity of i64s.

func StringStringMap ¶

func StringStringMap(m map[string]string) uint64

StringStringMap returns the accumulated identity of m.

Types ¶

type Accumulator ¶

type Accumulator uint64

Accumulator is a commutative folding accumulator.

func NewAccumulator ¶

func NewAccumulator() Accumulator

NewAccumulator creates a new Accumulator with a default seed value.

n.b. Here and elsewhere, we use nosplit to avoid stack size checks, which

are unnecessary as memory width is bounded to each instance of `a` (a
uint64) and, potentially, a single stack-local loop temporary while
iterating.

func NewAccumulatorWithSeed ¶

func NewAccumulatorWithSeed(seed uint64) Accumulator

NewAccumulatorWithSeed creates a new Accumulator with the provided seed value.

func (Accumulator) AddString ¶

func (a Accumulator) AddString(str string) Accumulator

AddString hashes str and folds it into the accumulator.

func (Accumulator) AddUint64 ¶

func (a Accumulator) AddUint64(u64 uint64) Accumulator

AddUint64 folds u64 into the accumulator.

func (Accumulator) Value ¶

func (a Accumulator) Value() uint64

Value returns the accumulated value.
