varint

Varint encoder/decoder

Implementation of a variable-length integer encoding scheme.

Varints are a common encoding for variable-length integer data, used in libraries such as sqlite, protobuf, v8, and more.

Here’s a quick and dirty module to help avoid reimplementing the same thing over and over again.

encode(number)

Pack number into varint bytes

decode_stream(stream)

Read a varint from stream

decode_bytes(buf)

Read a varint from from buf bytes
