type CHD struct {
	StoreKeys        bool
	ValuesAreVarints bool
	// contains filtered or unexported fields
}

CHD hash table lookup.

func Mmap(b []byte, isVarints bool) (*CHD, error)

Mmap creates a new CHD aliasing the CHD structure over an existing byte region (typically mmapped).

func Read(r io.Reader) (*CHD, error)

Read a serialized CHD.

func ReadVarints(r io.Reader) (*CHD, error)

func (c *CHD) Get(key []byte) []byte

Get an entry from the hash table.

func (c *CHD) GetUint64(key []byte) (uint64, bool)

func (c *CHD) Iterate() *Iterator

Iterate over entries in the hash table.

func (c *CHD) Len() int

func (c *CHD) Write(w io.Writer) error

Serialize the CHD. The serialized form is conducive to mmapped access. See the Mmap function for details.

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

Build a new CDH MPH.

func Builder(size int) *CHDBuilder

Create a new CHD hash table builder.

func Uvarint64Builder(size int) *CHDBuilder

func (b *CHDBuilder) Add(key []byte, value []byte)

Add a key and value to the hash table.

func (b *CHDBuilder) AddUvarint64(key []byte, value uint64)

AddUvarint64 a key and value to the hash table.

func (b *CHDBuilder) Build() (*CHD, error)

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

func (c *Iterator) Get() (key []byte, value []byte)

func (c *Iterator) Next() *Iterator
