Types

type MapVerifier

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

MapVerifier verifies inclusion of key/values in a map.

func NewMapVerifier

func NewMapVerifier(tileFetch TileFetch, prefixStrata int, treeID int64, hash crypto.Hash) *MapVerifier

NewMapVerifier returns a MapVerifier for the map at the given location and with the configuration provided.

func (*MapVerifier) CheckInclusion

func (v *MapVerifier) CheckInclusion(rev int, key string, value []byte) ([]byte, error)

CheckInclusion confirms that the key & value are committed to by the map in the given directory, and returns the computed and confirmed root hash that commits to this.

type TileFetch

type TileFetch func(revision int, path []byte) (*batchmap.Tile, error)

TileFetch gets the tile at the specified path in the given map revision. There is currently an assumption that this is very fast and thus it looks up tiles one at a time. This can be replaced with a batch version if that assumption is invalidated (e.g. this method triggers network operations).
