Functions

func CloneByteSlice

func CloneByteSlice(bytes []byte) []byte

CloneByteSlice clones a slice of bytes, as slices.Clone would do, but does not allocate extra space.

func ConcatByteSlices

func ConcatByteSlices(slices ...[]byte) []byte

ConcatByteSlice concatenates a byte slices, as slices.Concat would do, but does not allocate extra space.

func IsNil

func IsNil(value any) bool

IsNil checks if interface or its value is nil.

func UpdateWithTx

func UpdateWithTx[T any](target *T, dirty T, tx TxFunc[T]) error

UpdateWithTx passes the dirty value to the transaction function and, if the transaction occurred without errors, replaces the target with the dirty version. This is useful for use in public methods to avoid corrupting the state with errors.

Types

type TxFunc

type TxFunc[T any] func(dirty *T) error
