Prior to this change, it's necessary to implement the entirety of the `WalletRead` trait in order to be able to use the input selection functionality provided by `zcash_client_backend::data_api::input_selection`. This change factors out the minimal operations required for transaction proposal construction to better reflect the principle of least authority and make the input selection code reusable in more contexts. In order to minimize the operations of the newly-created `InputSource` and `ShieldingSource` traits, this change also removes the `min_confirmations` field from transaction proposals, in favor of storing explicit target and anchor heights. This has the effect of limiting the lifetime of transaction proposals to `PRUNING_DEPTH - min_confirmations` blocks. |
