If we give the `DummySigner` a valid identifier then we can use this to
do comparison.
Half the time we do comparison we only have a `dyn Signer` so we cannot
use `PartialEq`, add a helper function to check equality (this is in
test code so its not toooo ugly).
Thanks @afilini for the suggestion.
Clippy emits error:
comparing trait object pointers compares a non-unique vtable address
The vtable is an implementation detail, it may change in future. we
should not be comparing vtable addresses for equality. Instead we can
get a pointer to the data field of a fat pointer and compare on that.
The `ChunksIterator` constructor is only used when either `electrum` or
`esplora` features are enabled. Conditionally build it so that we do not
get a clippy warning when building without these features.
Clippy emits warning:
warning: field assignment outside of initializer for an instance
created with Default::default()
Do as suggested by clippy and use the default init pattern.
```
let foo = Foo {
bar: ...,
Default::default()
}
```
As suggested by clippy we can use `.next()` on an iterator instead of
`nth(0)`. Although arguably no clearer, and certainly no worse, it keeps
clippy quiet and a clean lint is a good thing.
Clippy emits warning:
warning: avoid using `collect()` when not needed
As suggested by clippy just use `count` directly on the iterator instead
of `collect` followed by `len`.
Due to brain malfunction I made utxos into a BTree. This made a test
pass but is incorrect. The test itself was incorrect as per comment in
https://github.com/bitcoindevkit/bdk/pull/258#issuecomment-758370380
So I (1) reverted utxos back to a Vec, (2) fixed the test and expanded
the comment in the test.
Fixes#251
TxBuilders are now not created directly but are created through the
wallet with `build_tx` and `build_fee_bump`.
The advantages of this realised in this commit are:
1. Normal tx creation and fee bumping use the code internally. The only
difference between normal tx and fee bump is how the builder is created.
2. The TxBuilder now has a refernce to the wallet and can therefore
lookup things as methods are called on it. `add_utxo` now uses this to
look up UTXO deta when it is called (rather than having to do it and
possibly error later on).
To support these changes `get_utxo` and `get_descriptor_for_keychain`
public methods have been added to Wallet. I could have kept them
pub(crate) but they seem like fine APIs to have publicly.
A `[cfg(test)]` function is not as helpful as a macro since it can't be
called in the context of a doctest.
Also adds doctest_wallet macro which can be used to create a wallet in a
doctest.
The syntax now is pretty much the same as the normal descriptor syntax,
with the only difference that modifiers cannot be grouped together (i.e.
`sdv:older(144)` must be turned into `s:d:v:older(144)`.
This commit also fixes the timelock comparing logic in the policy module, since
the rules are different for absolute (OP_CLTV) and relative (OP_CSV) timelocks.
