Module varint 

Unsigned LEB128 varint encoding.

A varint encodes an unsigned integer in one to ten bytes. The low seven bits of each byte carry payload, and the top bit signals continuation: 1 means more bytes follow, 0 means the value is complete.

The encoding is identical to the format used by Protocol Buffers, WebAssembly, and DWARF.

Constants

MAX_LEN_U16

Maximum encoded length of a u16 varint.

MAX_LEN_U32

Maximum encoded length of a u32 varint.

MAX_LEN_U64

Maximum encoded length of a u64 varint.
