Enum Revision 

pub enum Revision {
    R0,
    R2,
}

The revision of ZIP 316 Unified Encoding used for a particular address or viewing key.

Revision 1 has no variant here because it was withdrawn before anything encoded it. It proposed transparent-permitting Unified Addresses that inspection could not tell apart from shielded-only ones, and Revision 2 supersedes it with the zu and tu prefixes, which make that distinction visible.

See ZIP 316 for details.

Variants

R0

Revision 0 of the unified encoding format.

This is the original format, which requires at least one shielded receiver in both Unified Addresses and Unified Viewing Keys.

R2

Revision 2 of the unified encoding format.

This revision adds metadata items, such as address expiry, and drops the requirement that a Unified Viewing Key contain a shielded item. A Unified Address carries the zu prefix when it has no transparent receiver, and the tu prefix when it has one.
