Functions

func MaybeWrapIfInvariants

func MaybeWrapIfInvariants(iter base.InternalIterator) base.InternalIterator

MaybeWrapIfInvariants wraps some iterators with an invalidating iterator. MaybeWrapIfInvariants does nothing in non-invariant builds.

func NewIter

func NewIter(originalIterator base.InternalIterator, opts ...Option) base.InternalIterator

NewIter constructs a new invalidating iterator that wraps the provided iterator, trashing buffers for previously returned keys.

Types

type Option

type Option interface {
	// contains filtered or unexported methods
}

Option configures the behavior of an invalidating iterator.

func IgnoreKinds

func IgnoreKinds(kinds ...base.InternalKeyKind) Option

IgnoreKinds constructs an Option that configures an invalidating iterator to skip trashing k/v pairs with the provided key kinds. Some iterators provided key stability guarantees for specific key kinds.
