Functions

func Bloom9

func Bloom9(b []byte) *big.Int

Types

type Bloom

type Bloom [BloomByteLength]byte

Bloom represents a 2048 bit bloom filter.

func BytesToBloom

func BytesToBloom(b []byte) Bloom

BytesToBloom converts a byte slice to a bloom filter.

func (*Bloom) Add

func (b *Bloom) Add(d *big.Int)

Add adds d to the filter. Future calls of Test(d) will return true.

func (Bloom) Big

func (b Bloom) Big() *big.Int

Big converts b to a big integer.

func (Bloom) Bytes

func (b Bloom) Bytes() []byte

Bytes converts b to bytes.

func (Bloom) MarshalText

func (b Bloom) MarshalText() ([]byte, error)

MarshalText encodes b as a hex string with 0x prefix.

func (*Bloom) SetBytes

func (b *Bloom) SetBytes(d []byte)

SetBytes sets the content of b to the given bytes.

func (*Bloom) UnmarshalText

func (b *Bloom) UnmarshalText(input []byte) error

UnmarshalText b as a hex string with 0x prefix.
