Kris Nuttycombe 2e2c161d52 Add a public bundle construction function & use it in the builder. 2023-12-18 21:56:42 -07:00
Kris Nuttycombe 06cb76168e Rename `Builder::add_recipient` to `add_output`. 
The term `recipient` is commonly used to refer to the address to which a
note is sent; however, a bundle may include multiple outputs to the same
recipient. This change is intended to clarify this usage.

Jack Grigg c4bf8105f2 Use `AssignedCell<NoteValue, _>` for circuit note values 2022-05-03 23:24:48 +00:00
Jack Grigg 70b6eb3623 Simplify witness synthesis for `v_net` 
`NoteValue - NoteValue` is always guaranteed to produce a valid
`ValueSum`, so we make that infallible and introduce a new helper method
`ValueSum::magnitude_sign` that we use for circuit synthesis.

Jack Grigg 5c5c999439 Move `orchard::bundle::Action` to its own module 
The `Bundle` struct is variable in size and requires allocations, but
`Action` is not. This split will make it cleaner to disable the bundle
logic for no-std support.

Jack Grigg b1d7787ab6 Re-introduce `ValueSum::from_raw` as a `pub(crate)` method 
We removed this in zcash/orchard#267 as it did not need to be part of
the public API, but we do still need a way to convert the user-defined
valueBalance type into a `ValueSum` when constructing `bvk`, and this
method is preferable to exposing the `ValueSum` internals.

Jack Grigg d11fbd4a56 Remove `ValueSum::from_raw` 
There is no reason for crate users to be constructing `ValueSum`
directly. We no longer use it to represent `valueBalanceOrchard`,
instead requiring the user to specify their own type.
