FromUvarint reads an unsigned varint from the beginning of buf, returns the varint, and the number of bytes read.

PutUvarint is an alias for binary.PutUvarint.

ReadUvarint reads a unsigned varint from the given reader.

ToUvarint converts an unsigned integer to a varint-encoded []byte.

UvarintSize returns the size (in bytes) of `num` encoded as a unsigned varint.

MaxLenUvarint63 is the maximum number of bytes representing an uvarint in this encoding, supporting a maximum value of 2^63 (uint63), aka MaxValueUvarint63.

MaxValueUvarint63 is the maximum encodable uint63 value.
