Functions

f decode deprecated	Given a non empty `buf`, starting at `offset` (default: 0), begin decoding bytes as VarInt encoded bytes, for a maximum of 10 bytes (offset + 10). The returned tuple is of the decoded varint 32-bit number, and the new offset with which to continue decoding other data.
f decode32 deprecated	Given a `buf`, starting at `offset` (default: 0), begin decoding bytes as VarInt encoded bytes, for a maximum of 5 bytes (offset + 5). The returned tuple is of the decoded varint 32-bit number, and the new offset with which to continue decoding other data.
f decodeVarint	Given a non empty `buf`, starting at `offset` (default: 0), begin decoding bytes as VarInt encoded bytes, for a maximum of 10 bytes (offset + 10). The returned tuple is of the decoded varint 32-bit number, and the new offset with which to continue decoding other data.
f decodeVarint32	Given a `buf`, starting at `offset` (default: 0), begin decoding bytes as VarInt encoded bytes, for a maximum of 5 bytes (offset + 5). The returned tuple is of the decoded varint 32-bit number, and the new offset with which to continue decoding other data.
f encode deprecated	Takes unsigned number `num` and converts it into a VarInt encoded `Uint8Array`, returning a tuple consisting of a `Uint8Array` slice of the encoded VarInt, and an offset where the VarInt encoded bytes end within the `Uint8Array`.
f encodeVarint	Takes unsigned number `num` and converts it into a VarInt encoded `Uint8Array`, returning a tuple consisting of a `Uint8Array` slice of the encoded VarInt, and an offset where the VarInt encoded bytes end within the `Uint8Array`.
