Clippy warns about creating a reference that is immediately
de-referenced.

Remove unnecessary explicit `&`, while we are at it remove unnecessary
explicit types that appear on the same lines of code.

Pull request description:

  As part of the ongoing error improvement work and as a direct result of [this comment](https://github.com/rust-bitcoin/rust-bitcoin/pull/987#issuecomment-1135563287) improve the `Display` implementations of all our error types so as to not repeat the source error when printing.

  The first 5 patches are trivial clean ups around the errors. Patch 6 is the real work.

  EDIT: ~CC @Kixunil, have I got the right idea here bro?~ Patch 6 now includes a macro as suggested.

Merge rust-bitcoin/rust-bitcoin#1006: Feature `use-serde` renamed to `serde`
2e7effc604 Feature `use-serde` renamed to `serde` (Martin Habovstiak)

Pull request description:

  Features activating external crates are supposed to have same name as
  those crates. However we depend on same feature in other crates so we
  need a separate feature. After MSRV bump it is possible to rename the
  crates and features so we can now fix this inconsistency.

  Sadly, derive can't see that the crate was renamed so all derives must
  be told to use the other one.

Tobin C. Harding 99f565f932 Add non_exhaustive to all error enums
Adding an error variant to a public enum is an API breaking change, this
means making what could be small refactorings or improvements harder. If
we use `non_exhaustive` for error types then we mitigate this cost.
There is a tradeoff however, downstream users who explicitly match on
our public error types must include a wildcard pattern.
2022-05-31 14:29:50 +10:00
Tobin C. Harding 57dd6739c3 Do not print error when displaying for std builds
We implement `source` for all our error types. This means that we should
not display the source error explicitly because users can call `source`
to get the source error.

However, `std::Error::source()` is only available for "std" builds, so
that we do not loose the error source information in "no-std" builds add
a macro that conditionally adds the source onto the error message.

Tobin Harding f92854a805 Add PSBT alias
Programmers are inherently lazy and for good reason. I'm yet to see
anyone write `PartiallySignedTransaction` in code that uses
`rust-bitcoin`, its too obvious to add a type alias for PSBTs, let's
just do it ourselves to save everyone else having to do so.

Add public type alias `Psbt` for `PartiallySignedTransaction`.

Tobin Harding 71cf00a314 Use less vertical lines
In this library we specifically do not use rustfmt and tend to favour

unnecessary number of lines.

None of these changes should reduce the readability of the code.

Separate merge logic out of Map trait
Recently we (*cough* Tobin) made the `Map` trait private and neglected
to add a public API for combining together two PSBTs. Doing so broke the
`psbt` module.

Pull the merge logic out of the `Map` trait and put it in methods on
each individual type (`Input`, `Output`, `PartiallySignedTransaction`).
Doing so allows for simplification of return types since combining
inputs/outputs never errors.

Use the term 'combine' instead of 'merge' since that is the term used in
BIP 174.

Introduce Witness struct mainly to improve ser/de performance while keeping most usability.
Witness struct is in place of the Vec<Vec<u8>> we have before this commit.

from_vec() and to_vec() methods are provided to switch between this type and Vec<Vec<u8>>

Moreover, implementation of Default, Iterator and others allows to have similar behaviour but
using a single Vec prevent many allocations during deserialization which in turns results in
better performance, even 20% better perfomance on recent block.

last() and second_to_last() allows to access respective element without going through costly Vec

  I took the most non-invasive approach to reduce diff size. Many parts of the code can be improved in style or further refactored (like some functions are not necessary and can be just moved to be part of other functions), but I'd prefer to do that as a separate PR once this will be merged.

  My approach with this PR:
  1. Remove `Global` struct by moving its fields right into `PartiallySignedTransaction` - but keep the `util/psbt/map/global.rs` file with all its logic
  2. Keep existing `Map for Global` implementation in the same file, but just change it to `Map for PartiallySignedTransaction`
  3. With serialization, convert `Global` deserialization into crate-private function and use it from `PartiallySignedTransaction` deserialization
  4. Refactor the tests and imports as required to get the thing compile and pass tests

  The refactoring will be followed by PR(s) adding support for Taproot

Tobin Harding 3f5caa501f Clean up module level rustdocs
Docs can always do with a bit of love.

Clean up the module level (`//!`) rustdocs for all public modules.

I claim uniform is better than any specific method/style. I tried to fit
in with what ever was either most sane of most prevalent, therefore
attaining uniformity without unnecessary code churn (one exception being
the changes to headings described below).

Notes:

* Headings - use heading as a regular sentence for all modules e.g.,

```
//! Bitcoin network messages.
```

as opposed to
```
//! # Bitcoin Network Messages
```

It was not clear which style to use so I picked a 'random' mature
project and copied their style.

* Added 'This module' in _most_ places as the start of the module
description, however I was not religious about this one.

* Fixed line length if necessary since most of our code seems to follow
short (80 char) line lengths for comments anyways.

* Added periods and fixed obvious (and sometimes not so obvious)
grammatically errors.

* Added a trailing `//!` to every block since this was almost universal
already. I don't really like this one but I'm guessing it is Andrew's
preferred style since its on the copyright notices as well.

Martin Habovstiak 95fb4e01f9 Document cargo features
This documents cargo features in two ways: explictly in text and in code
using `#[doc(cfg(...))]` attribute where possible. Notably, this is
impossible for `serde` derives. The attribute is contitional and only
activated for docs.rs or explicit local builds.

This change also adds `package.metadata.docs.rs` field to `Cargo.toml`
which instructs docs.rs to build with relevant features and with
`docsrs` config activated enabling `#[doc(cfg(...))] attributes.

I also took the opportunity to fix a few missing spaces in nearby code.
