Function EncodingPartsForBitLen

pkg/util/bitarray/bitarray.go:295–302

EncodingPartsForBitLen creates a word backing array and the "last bits used" value given the given total number of bits.

(bitLen uint)

// SizesForBitLen computes the number of words and last bits used for
// the requested bit array size.
