Struct internet2::presentation::BigSize

pub struct BigSize(_);

Lightning TLV uses a custom variable-length integer called BigSize. It is similar to Bitcoin's variable-length integers except that it is serialized in big-endian instead of little-endian.

BigSize specification is given at https://github.com/lightningnetwork/lightning-rfc/blob/master/01-messaging.md#type-length-value-format

Like Bitcoin's variable-length integer, it exhibits ambiguity in that certain values can be encoded in several different ways, which we must check for at deserialization-time. Thus, if you're looking for an example of a variable-length integer to use for your own project, move along, this is a rather poor design.
