NewDB constructs a new DB and validates the schema if it exists in database on the given path.

DB provides abstractions over LevelDB in order to implement complex structures using fields and ordered indexes.

Index represents a set of LevelDB key value pairs that have common prefix.

IndexFuncs structure defines functions for encoding and decoding LevelDB keys and values for a specific index.

Item holds fields relevant to Swarm Chunk data and metadata.

IterateOptions defines optional parameters for Iterate function.

StringField is the most simple field implementation that stores an arbitrary string under a specific LevelDB key.

StructField is a helper to store complex structure by encoding it in RLP format.

Uint64Field provides a way to have a simple counter in the database.

IndexIterFunc is a callback on every Item that is decoded by iterating on an Index keys.
