func (*Bitmap) Bit ¶

func (b *Bitmap) Bit(i int) uint

Bit returns the value of the i'th bit of b. The bit index i must be >= 0.

func (*Bitmap) Bytes ¶

func (b *Bitmap) Bytes() []byte

Bytes returns the absolute value of b as a big-endian byte slice.

func (*Bitmap) Range ¶

func (b *Bitmap) Range(s, e int) *Bitmap

Range returns bits [s, e) as another bitmap.

func (*Bitmap) SetBit ¶

func (b *Bitmap) SetBit(i int, v uint)

SetBit sets b's i'th bit to v (0 or 1). If b is not 0 or 1, SetBit will panic.

func (*Bitmap) SetBytes ¶

func (b *Bitmap) SetBytes(buf []byte)

SetBytes interprets buf as the bytes of a big-endian unsigned integer, and sets b to that value.

func (*Bitmap) SetString ¶

func (b *Bitmap) SetString(s string) bool

SetString sets b to the value of s, interpreted in the given base, and returns a boolean indicating success.

A prefix of “0b” or “0B” selects base 2, “0”, “0o” or “0O” selects base 8, and “0x” or “0X” selects base 16. Otherwise, the selected base is 10 and no prefix is accepted.

func (*Bitmap) SetUint64 ¶

func (b *Bitmap) SetUint64(x uint64)

SetUint64 sets b to x.

func (*Bitmap) Size ¶

func (b *Bitmap) Size() int

func (*Bitmap) String ¶

func (b *Bitmap) String(base int) string

String returns the string representation of b in the given base. Base must be between 2 and 62, inclusive.

func (*Bitmap) Uint64 ¶

func (b *Bitmap) Uint64() (uint64, bool)

Uint64 returns the uint64 representation of b. If b cannot be represented in a uint64, Uint64 will return (0, false).
