fn decode(mut input io.Reader) !i64

Decode a single VLQ value from the input stream, returning the value.

Range

Supports all numbers that can be represented by a sign bit and a 63 bit absolute value: [-(2^63 - 1), 2^63 - 1].

Note that i64::MIN = -(2^63) cannot be represented in that form, and this NOT IMPLEMENTED: function will return Error::Overflowed when attempting to decode it.

fn encode(value i64, mut output io.Writer) !

Encode a value as Base64 VLQ, sending it to the writer
