4d2291930b Use fragment-specifier literal (Tobin C. Harding)
Pull request description:
Currently we are using the fragment-specifier `expr` in a bunch of
macros for captures that are only used for literals. If we use `literal`
instead it allows the compiler to give slightly more specific error
messages.
The benefits of this change are minor. Of note, this patch found one
unusual macro call site (removed unnecessary `&`).
The macros changed are all internal macros, this is not a breaking change.

clippy emits a bunch of:
warning: digits grouped inconsistently by underscores
We have a custom grouping elsewhere in this file
10_000_000_00 sats == 10 BTC
Fix up all instances of large sats amount to uniformly using this format
and add compiler directives where needed to shoosh clippy.

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.
Replaces #373

99f565f932 Add non_exhaustive to all error enums (Tobin C. Harding)
Pull request description:
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.

Rust convention is to use `to_` for conversion methods that convert from
an owned type to an owned `Copy` type. `as_` is for borrowed to borrowed
types.
Re-name and deprecate conversion methods that use `as_` for owned to
owned `Copy` types to use `to_`.

Currently we allow multiple trailing colons when matching within the
`check_format_non_negative` macro. We can be more restrictive with no
loss of usability.
Use `$(;)?` instead of `$(;)*` to match against 0 or 1 semi-colons
instead of 0 or more.

No manual changes made. The result of the command above is just to fix
all the use statements (add `crate::`) and fix the fully qualified path
formats i.e., `::Foo` -> `crate::Foo`.
4f1200d629 Added `amount::Display` - configurable formatting (Martin Habovstiak)
Pull request description:
This significatnly refactors the formatting code to make formatting more
configurable. The main addition is the `Display` type which is a
builder that can configure denomination or other things (possibly more
in the future).
Further, this makes all representations of numbers minimal by default,
so should be documented as a possibly-breaking change.
Because of the effort to support all other `fmt::Formatter` options this
required practically complete rewrite of `fmt_satoshi_in`. As a
byproduct I took the opportunity of removing one allocation from there.

The exact code formatting we use is not as important as uniformity.
Since we do not use tooling to control the formatting we have to be
vigilant ourselves. Recently I (Tobin) changed the way default type
parameters were formatted (arbitrarily but uniformly). Turns out I
picked the wrong way, there is already a convention as shown in the rust
documentation online (e.g. [1]).
Use 'conventional' spacing for default type parameters. Make the change
across the whole repository, found using
git grep '\<.* = .*\>'

In this library we specifically do not use rustfmt and tend to favour
terse statements that do not use extra lines unnecessarily. In order to
help new devs understand the style modify code that seems to use an
unnecessary number of lines.
None of these changes should reduce the readability of the code.
Our usage of `where` statements is not uniform, nor is it inline with
the typical layout suggested by `rustfmt`.
Make an effort to be more uniform with usage of `where` statements.
However, explicitly do _not_ do every usage since sometimes our usage
favours terseness (all on a single line).
Do various whitespace refactorings, of note:
- Use space around equals e.g., 'since = "blah"'
- Put return/break/continue on separate line
Whitespace only, no logic changes.
f690b8e362 Be more liberal when parsing Denomination (Tobin Harding)
628168e493 Add missing white space character (Tobin Harding)
Pull request description:
There is no reason to force users to use a particular format or case for `Denomination` strings. Users may wish to write any of the following and all seem reasonable
- 100 sats
- 100 sat
- 100 SAT
The same goes for various other `Denomination`s.
- Patch 1 enables usage of "sats", "sat", "bit", "bits"
- Patch 2 enables usage of various lower/uper case formatting

There is no reason to force users to use one particular form when
providing a denomination string. We can be liberal in what we accept
with no loss of clarity.
Allow `Denomination` strings to use a variety of forms, in particular
lower case and uppercase.
Note, we explicitly disallow various forms of `Msat` because it is
ambiguous whether this means milli or mega sats.

This is the initial step towards using and maybe enforcing clippy.
It does not fix all lints as some are not applicable. They may be
explicitly ignored later.
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.
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.
Based on the original work by Justin Moon.
*MSRV unchanged from 1.29.0.*
When `std` is off, `no-std` must be on, and we use the [`alloc`](https://doc.rust-lang.org/alloc/) and core2 crates. The `alloc` crate requires the user define a global allocator.
* Import from `core` and `alloc` instead of `std`
* `alloc` only used if `no-std` is on
* Create `std` feature
* Create `no-std` feature which adds a core2 dependency to polyfill `std::io` features. This is an experimental feature and should be
used with caution.
* CI runs tests `no-std`
* MSRV for `no-std` is 1.51 or so
