Helper method docs are updated to explain what they are updating. Logic
is simplified as we do not need to check whether a tx exists already in
`update_graph` before inserting it.
The previous `TxOut` for transactions received from an external
wallet may be optionally added as floating `TxOut`s to `TxGraph`
to allow for fee calculation.
This is more code, but a much more elegant solution than having
`ElectrumExt` methods return `SyncResult`/`FullScanResult` and having an
`ElectrumResultExt` extention trait.
`ElectrumResultExt` trait is also introduced that adds methods which can
convert the `Anchor` type for the update `TxGraph`.
We also make use of the new `TxCache` fields in
`SyncRequest`/`FullScanRequest`. This way, we can avoid re-fetching full
transactions from Electrum if not needed.
Examples and tests are updated to use the new `ElectrumExt` API.
This PR removes `RelevantTxids` from the electrum crate and tracks
transactions in a `TxGraph`. This removes the need to separately
construct a `TxGraph` after a `full_scan` or `sync`.
This fixes the bug with changesets not being monotone. Previously, the
result of applying changesets individually v.s. applying the aggregate
of changesets may result in different `KeychainTxOutIndex` states.
The nature of the changeset allows different keychain types to share the
same descriptor. However, the previous design did not take this into
account. To do this properly, we should keep track of all keychains
currently associated with a given descriptor. However, the API only
allows returning one keychain per spk/txout/outpoint (which is a good
API).
Therefore, we rank keychain variants by `Ord`. Earlier keychain variants
have a higher rank, and the first keychain will be returned.
We only need to loop though entries of `other`. The logic before was
wasteful because we were also looping though all entries of `self` even
if we do not need to modify the `self` entry.
- The KeychainTxOutIndex's internal SpkIterator now uses DescriptorId
instead of K. The DescriptorId -> K translation is made at the
KeychainTxOutIndex level.
- The keychain::Changeset is now a struct, which includes a map for last
revealed indexes, and one for newly added keychains and their
descriptor.
API changes in bdk:
- Wallet::keychains returns a `impl Iterator` instead of `BTreeMap`
- Wallet::load doesn't take descriptors anymore, since they're stored in
the db
- Wallet::new_or_load checks if the loaded descriptor from db is the
same as the provided one
API changes in bdk_chain:
- `ChangeSet` is now a struct, which includes a map for last revealed
indexes, and one for keychains and descriptors.
- `KeychainTxOutIndex::inner` returns a `SpkIterator<(DescriptorId, u32)>`
- `KeychainTxOutIndex::outpoints` returns a `impl Iterator` instead of `&BTreeSet`
- `KeychainTxOutIndex::keychains` returns a `impl Iterator` instead of
`&BTreeMap`
- `KeychainTxOutIndex::txouts` doesn't return a ExactSizeIterator
anymore
- `KeychainTxOutIndex::unbounded_spk_iter` returns an `Option`
- `KeychainTxOutIndex::next_index` returns an `Option`
- `KeychainTxOutIndex::last_revealed_indices` returns a `BTreeMap`
instead of `&BTreeMap`
- `KeychainTxOutIndex::reveal_to_target` returns an `Option`
- `KeychainTxOutIndex::reveal_next_spk` returns an `Option`
- `KeychainTxOutIndex::next_unused_spk` returns an `Option`
- `KeychainTxOutIndex::add_keychain` has been renamed to
`KeychainTxOutIndex::insert_descriptor`, and now it returns a
ChangeSet
We plan to record `Descriptor` additions into persistence. Hence, we
need to add `Descriptor`s to the changeset. This depends on
`miniscript`. Moving this into `txout_index.rs` makes sense as this is
consistent with all the other files. The only reason why this wasn't
this way before, is because the changeset didn't need miniscript.

Pull request description:
### Description
This PR adds a `default` feature to `bdk_persist` so it can be build on its own. Once #1422 is done we can remove the `default`again.
### Notes to the reviewers
I need to be able to build `bdk_persist` on its own so I can publish it to crates.io.

Pull request description:
fixes#823
<!-- You can erase any parts of this template not applicable to your Pull Request. -->
### Description
It's being used on `Balance`, and throughout the code, an `u64` represents the amount, which relies on the user to infer its sats, not millisats, or any other representation.
It updates the usage of `u64` on `Balance`, and other APIs:
- `TxParams::add_recipient`
- `KeyChainTxOutIndex::sent_and_received`, `KeyChainTxOutIndex::net_value`
- `SpkTxOutIndex::sent_and_received`, `SpkTxOutIndex::net_value`
<!-- Describe the purpose of this PR, what's being adding and/or fixed -->
### Notes to the reviewers
<!-- In this section you can include notes directed to the reviewers, like explaining why some parts
of the PR were done in a specific way -->
It updates some of the APIs to expect the `bitcoin::Amount`, but it does not update internal usage of u64, such as `TxParams` still expects and uses `u64`, please see the PR comments for related discussion.
### Changelog notice
<!-- Notice the release manager should include in the release tag message changelog -->
<!-- See https://keepachangelog.com/en/1.0.0/ for examples -->
- Changed the `keychain::Balance` struct fields to use `Amount` instead of `u64`.
- Changed the `add_recipient` method on `TxBuilder` implementation to expect `bitcoin::Amount`.
- Changed the `sent_and_received`, and `net_value` methods on `KeyChainTxOutIndex` to expect `bitcoin::Amount`.
- Changed the `sent_and_received`, and `net_value` methods on `SpkTxOutIndex` to expect `bitcoin::Amount`.

Pull request description:
<!-- You can erase any parts of this template not applicable to your Pull Request. -->
### Description
Reexports `electrsd` in `TestEnv` to remove the `electrsd` dev depedency out of `bdk_electrum` and `bdk_esplora`.
Credit to @ValuedMammal for the idea.
Since `bitcoind` reexports `anyhow`, this dev dependency was also removed from `bdk_electrum`, `bdk_esplora`, and `bdk_bitcoind_rpc`. `bitcoind`, `bitcoincore_rpc` and `electrum_client` were also reexported for convenience.
### Changelog notice
* Change `bdk_testenv` to re-export internally used crates.

Pull request description:
Fixes#1354
### Description
Built on top of both #1369 and #1373, we simplify the `EsploraExt` API by removing the `update_local_chain` method and having `full_scan` and `sync` update the local chain in the same call. The `full_scan` and `sync` methods now takes in an additional input (`local_tip`) which provides us with the view of the `LocalChain` before the update. These methods now return structs `FullScanUpdate` and `SyncUpdate`.
The examples are updated to use this new API. `TxGraph::missing_heights` and `tx_graph::ChangeSet::missing_heights_from` are no longer needed, therefore they are removed.
Additionally, we used this opportunity to simplify the logic which updates `LocalChain`. We got rid of the `local_chain::Update` struct (which contained the update `CheckPoint` tip and a `bool` which signaled whether we want to introduce blocks below point of agreement). It turns out we can use something like `CheckPoint::insert` so the chain source can craft an update based on the old tip. This way, we can make better use of `merge_chains`' optimization that compares the `Arc` pointers of the local and update chain (before we were crafting the update chain NOT based on top of the previous local chain). With this, we no longer need the `Update::introduce_older_block` field since the logic will naturally break when we reach a matching `Arc` pointer.
### Notes to the reviewers
* Obtaining the `LocalChain`'s update now happens within `EsploraExt::full_scan` and `EsploraExt::sync`. Creating the `LocalChain` update is now split into two methods (`fetch_latest_blocks` and `chain_update`) that are called before and after fetching transactions and anchors.
* We need to duplicate code for `bdk_esplora`. One for blocking and one for async.
### Changelog notice
* Changed `EsploraExt` API so that sync only requires one round of fetching data. The `local_chain_update` method is removed and the `local_tip` parameter is added to the `full_scan` and `sync` methods.
* Removed `TxGraph::missing_heights` and `tx_graph::ChangeSet::missing_heights_from` methods.
* Introduced `CheckPoint::insert` which allows convenient checkpoint-insertion. This is intended for use by chain-sources when crafting an update.
* Refactored `merge_chains` to also return the resultant `CheckPoint` tip.
* Optimized the update `LocalChain` logic - use the update `CheckPoint` as the new `CheckPoint` tip when possible.

`merge_chains` now returns a tuple of the resultant checkpoint AND
changeset. This is arguably a more readable/understandable setup.
To do this, we had to create `CheckPoint::apply_changeset` which is kept
as a private method.
Thank you @ValuedMammal for the suggestion.

d3a14d411d2a1a37f07e42c28eae3a1836aec14d fix: enable blocking-https-rustls feature on esplora client (thunderbiscuit)
Pull request description:
The [`blocking` feature on the rust-esplora-client library](https://github.com/bitcoindevkit/rust-esplora-client/blame/master/Cargo.toml#L35) changed from ureq to minreq, which does not come with https enabled by default, breaking previously working code that simply enabled the `blocking` feature on the `bdk_esplora` crate.
This change will enable what is currently the "default https" [flag for the minreq library](https://docs.rs/minreq/latest/minreq/#https-or-https-rustls) when using the `blocking` feature on bdk_esplora, reverting that breaking change.
### Notes to the reviewers
Another way we could do this (let me know if this is preferable) is to add a new feature called `blocking-https-rustls`:
```rust
blocking = ["esplora-client/blocking"]
blocking-https-rustls = ["esplora-client/blocking-https-rustls"]
```
