DecodeInt decodes the array of bytes and returns a signed 64-bit integer.

DecodeUInt decodes the array of bytes and returns an unsigned 64-bit integer.

DecodeUIntRev decodes the varint encoded by EncodeUIntRev[InPlace].

EncodeInt encodes the signed 64-bit integer value into a varint and returns an array of bytes (little endian encoded).

EncodeUInt encodes the unsigned 64-bit integer value into a varint and returns an array of bytes (little endian encoded).

EncodeUIntRevInPlace encodes the uint64 value into a reversed-varint in place, produce the same result as slices.Reverse(EncodeUInt(x)).

GetEncodeUIntSize returns the size in byte the encoded varint will take.
