Method get32BitsFast

zstd/bitreader.go:60–65

get32BitsFast requires that at least one bit is requested every time. There are no checks if the buffer is filled.

(n uint8)

// get32BitsFast requires that at least one bit is requested every time.
// There are no checks if the buffer is filled.
func (b *bitReader) get32BitsFast(n uint8) uint32 {
	const regMask = 64 - 1
	v := uint32((b.value << (b.bitsRead & regMask)) >> ((regMask + 1 - n) & regMask))
	b.bitsRead += n
	return v
}

// fillFast() will make sure at least 32 bits are available.
// There must be at least 4 bytes available.
