Functions

func Detach

func Detach(ctx context.Context) context.Context

func Err

func Err(errors ...error) error

func GetStacktrace

func GetStacktrace(all bool) string

func IsSortedAndUnique

func IsSortedAndUnique[T Sortable[T]](s []T) bool

Returns true iff the elements in [s] are unique and sorted.

func IsSortedAndUniqueByHash

func IsSortedAndUniqueByHash[T ~[]byte](s []T) bool

Returns true iff the elements in [s] are unique and sorted based by their hashes.

func IsSortedAndUniqueOrdered

func IsSortedAndUniqueOrdered[T constraints.Ordered](s []T) bool

Returns true iff the elements in [s] are unique and sorted.

func IsSortedBytes

func IsSortedBytes[T ~[]byte](s []T) bool

Returns true iff the elements in [s] are sorted.

func RandomBytes

func RandomBytes(n int) []byte

RandomBytes returns a slice of n random bytes Intended for use in testing

func Sort

func Sort[T Sortable[T]](s []T)

Sorts the elements of [s].

func SortByHash

func SortByHash[T ~[]byte](s []T)

Sorts the elements of [s] based on their hashes.

func SortBytes

func SortBytes[T ~[]byte](s []T)

Sorts a 2D byte slice. Each byte slice is not sorted internally; the byte slices are sorted relative to one another.

func Zero

func Zero[T any]() T

Returns a new instance of a T.

func ZeroSlice

func ZeroSlice[T any](s []T)

ZeroSlice sets all values of the provided slice to the type's zero value.

This can be useful to ensure that the garbage collector doesn't hold references to values that are no longer desired.

Types

type Atomic

type Atomic[T any] struct {
	// contains filtered or unexported fields
}

func (*Atomic[T]) Get

func (a *Atomic[T]) Get() T

func (*Atomic[T]) Set

type AtomicBool

type AtomicBool struct {

type AtomicInterface

type AtomicInterface struct {
	// contains filtered or unexported fields
}

func NewAtomicInterface

func NewAtomicInterface(v interface{}) *AtomicInterface

func (*AtomicInterface) GetValue

func (a *AtomicInterface) GetValue() interface{}

func (*AtomicInterface) SetValue

func (a *AtomicInterface) SetValue(v interface{})
