type Database ¶

type Database struct {

}

Database is an in-memory implementation of HeightIndex. It provides thread-safe height-based key-value storage for testing and high-performance paths.

func New ¶

func New() *Database

New creates a new in-memory HeightIndex database.

func (*Database) Close ¶

func (db *Database) Close() error

Close releases resources and clears all stored data. Subsequent operations will return database.ErrClosed.

func (*Database) Delete ¶

func (db *Database) Delete(height uint64) error

Delete removes the value at the given height. Does not return an error if the height does not exist.

func (*Database) Get ¶

func (db *Database) Get(height uint64) ([]byte, error)

Get retrieves the value at the given height. Returns database.ErrNotFound if the height does not exist. The returned byte slice is safe to read, but cannot be modified.

func (*Database) Has ¶

func (db *Database) Has(height uint64) (bool, error)

Has returns whether a value exists at the given height.

func (*Database) Put ¶

func (db *Database) Put(height uint64, value []byte) error
