Types

type For

type For interface {
	Mutate
	Query
}

For exposes actions that are bound to a specific Prefixed

type Iterable

type Iterable interface {
	All() Iterator
	From(value.Key) Iterator
}

Iterable can be used to generate an Iterator

type Iterator

type Iterator func() (value.Key, any, Iterator, bool)

Iterator is stateless iteration interface

type Mutate

type Mutate interface {
	Insert(value.Key, any) (any, bool)
	Delete(value.Key) (any, bool)
	Drop() bool
}

Mutate allows changed to data of a Prefixed For

type Query

type Query interface {
	Get(value.Key) (any, bool)
	Ascending() Iterable
	Descending() Iterable
}

Query allows retrieval of data from a Prefixed For

type Txn

type Txn interface {
	For(prefix.Prefixed) For
}

Txn manages the types of actions that can be performed at the most basic level of the storage system
