lib.rs:

Data modeling for Penumbra transactions.

This crate defines data structures that provide modeling of shielded transactions through their entire lifecycle:

• the TransactionPlan type completely describes a planned transaction before it is created;

• the Transaction type represents the shielded transaction itself;

• the TransactionView type represents a view from a particular TransactionPerspective (e.g., the sender or receiver) of the cleartext contents of a shielded transaction after it has been created.
