The ShieldedData container for the spend and output descriptions of a
transaction does *not* move, because it's encoding transaction
structure. A good sign that this is the right factoring is that the
transaction module now only needs to pull in sapling::{Spend, Output}
and not all the internals.
This is the first in a sequence of changes that change the block:: items
to not include Block as a prefix in their name, in accordance with the
Rust API guidelines.
This Merkle tree is the SHA256d one used only for including transactions
in a block, so it should be kept there in order to not be confused with
other Merkle trees (like the note commitment trees).
It's not accurate to call it a LightClientRootHash, because it's not
always a root has for a light client -- sometimes it's a different kind
of root hash.
This moves the tests::generate module into the block tests. Because
this whole set of changes is just focused on reorganization, the
generate code is unchanged, but in the future, the code should be
rewritten as a collection of proptest strategies.
This extracts the `difficulty` module from `block` and the
`equihash_solution` module from the crate root. The PoW calculations
are significantly more complicated than the other block code and pretty
dissimilar from it, so it makes more sense to create a common proof of
work module.
The `EquihashSolution` and `EQUIHASH_SOLUTION_SIZE` are renamed to
`equihash::Solution` and `equihash::SOLUTION_SIZE` and imported that
way, except in `block/header.rs`, to avoid a conflict with the
`equihash` crate. In the future it would be better to encapsulate the
equihash solution check into the `equihash::Solution` type so that
callers only need to import our `work::equihash`.
The test organization leaves a little to be desired but I think that
this can be improved as we fill out the proof of work implementation.
This moves the transaction strategies to `arbitrary`, to live with the
other strategy impls (`Arbitrary` is just a default type-associated
strategy), splits the proptests into a new `prop` module, and splits the
test vector checks into a `vector`s module.
This ensures that we keep code in leaf modules and only have
organization (use statements) in non-leaf modules.
This extracts the SHA256d code from being split across two modules and puts it
in one module, under serialization.
The code is unchanged except for three deleted tests:
* `sha256d_flush` in `sha256d_writer` (not a meaningful test);
* `transactionhash_debug` (constructs an invalid transaction hash, and the
behavior is tested in the next test);
* `decode_state_debug` (we do not need to test the Debug output of
DecodeState);
* feature: Implement CompactDifficulty to Work
* fix: Test Work on all difficulty test cases
* fix: Add Bitcoin test vectors for difficulty
* feature: Cumulative Work
* impl Add, AddAssign for Work
* derive Default for Work
* test cumulative work
* fix: comments
* fix: More comments
* Fix comment links
* Remove unused import
