New clippy lint in rustc nightly "lifetime flowing from input to output
with different syntax can be confusing".
Apply the suggested fix and use the anonymous lifetime for paths.
To get more precision use sats per million virtual bytes.
To make review easier keep most calls in tests using
`FeeRate::from_sats_per_kwu` and just unwrap. These can likely be
cleaned up later on if we want to.
For `serde` just change the module to `_floor` and leave it at that. The
serde stuff likely needs re-visiting before release anyways.
In preparation for changing the internal representation of `FeeRate` to
use MvB reduce the max value by 4_000.
Done separately to make the change explicit.
The `FeeRate::checked_mul_by_weight` function currently returns a
`NumOpResult` but all other `checked_` functions return an `Option`.
This is surprising and adds no additional information.
Change `checked_mul_by_weight` to return `None` on overflow. But in
`to_fee` saturate to `Amount::MAX` because doing so makes a few APIs
better without any risk since a fee must be checked anyway so
`Amount::MAX` as a fee is equally descriptive in the error case.
This leads to removing the `NumOpResult` from `effective_value` also.
Note that sadly we remove the very nice docs on `NumOpResult::map`
because they no longer work.
Fix: #4497
This type creates sane Arbitrary InputWeightPrediction types that do
not panic. To this end, when a custom type is created by calling new()
or from_slice() constructor, only use values that would no greater than
block size 4 Mwu.

Prefer the more informative return type NumOpResult over Option. Also a returns section was added which describes the different possible returns.
The api of NumOpResult could probably be extended to cleanup the match statement. Also consider api addition for unchecked calculations natively.

Prefer the more descriptive NumOpResult return type over Option where
return types are fallible.
The returned type NumOpResult is already annotated as must_use per the
lint, so must_use can be removed after changing the method return types
to NumOpResult.
This is not a generic UNIX timestamp, but rather a MTP restricted to
have values between 500 million and u32::MAX. Most importantly, it is
*not* a blocktime, which is what is implied by its name and
constructors.

we replace Option<Amount> return type with Amount in minimal_non_dust
- Use `.expect("dust_relay_fee or script length should not be absurdly large")` to handle overflow from .checked_mul()
`.expect()` is only triggered if the value calculateed overflows u64

This is making PRs around releasing and depending on the release more

Use `hex_lit::hex` where possible (often needing an additional call to
`to_vec()`) and where not possible use `Vec::from_hex`.
We can use `deserialize_hex` when outside of the actual benchmark code
to simplify the functions.
Also add an additional test that benchmarks `deserialize_hex`.
InputWeightPrediction can be used to determine the weight needed
to calculate the effective_value. This simplifies the process for api
consumers by allowing an easier interface with which to use to predict
the weight. Prior to this change, it was required to manually calculate
the predicted weight for whichever input type was to be used.
Calculating the minimum non-dust fee currently panics if either the
script is really big or the dust fee rate is really big.
Harden the API by returning an `Option` instead of panicing.

This fixes issue #4141
Change count_witness_sigops and count_p2sh_sigops to take the spent
closure by value instead of &mut
- Changed both functions to accept S as a value (FnMut) instead of &mut S
- Removes need to annotate &mut when calling the function
This commit addresses #4041 by making the transaction::Version field private
Changes:
- Make the `Version` field private with `pub(crate)`
- Rename `non_standard` to `maybe_non_standard` for clarity since it accepts both standard and non-standard versions
- Add `#[inline]` attributes to small, frequently used methods:
- `as_u32`
- `maybe_non_standard`
Users now must use either:
- Constants (`Version::ONE/TWO/THREE`) for standard versions
- `maybe_non_standard` method for any version (standard or non-standard)
6244cb75fa Introduce monadic AmountOpResult (Tobin C. Harding)

We would like to return an error when doing math ops on amount types. We cannot however use the stdlib `Result` or `Option` because we want to implement ops on the result type.
Add an `NumOpResult` type. Return this type from all math operations on `Amount` and `SignedAmount`.
Implement `core::iter::Sum` for the new type to allow summing iterators of amounts.

We would like to return an error when doing math ops on amount types.
We cannot however use the stdlib `Result` or `Option` because we want to
implement ops on the result type.
Add an `AmountOpResult` type. Return this type from all math operations
on `Amount` and `SignedAmount`.
Implement `core::iter::Sum` for the new type to allow summing iterators
of amounts - somewhat ugly to use, see tests for example usage.
Currently `InputString` is in the public API of `units` because of the
trait bound on `parse::int()`. We can just do the monomorphisisation
manually to remove it.
This patch renames `int` to have three different names, one for `&str`
one for `String`, and one for `Box<str>`.
Any SignedAmount can now be cast to Amount since the range is the same.
Specifically, the range for SignedAmount is (- 21 million, 21 million)
while the range for Amount is (0, 21 million). Therefore any value from
Amount can be cast to a SignedAmount and it will work. Note it's not
the same and still requires checking when going from SignedAmount to
Amount since Amount can't handle the negative range.
As a side effect of changing the return type, TryFrom is no longer valid
and does not compile. Therefore in addition to changing the return
type, TryFrom is also removed.

3c8c956511 Remove Weight::from_wu_usize function (Tobin C. Harding)
Pull request description:
This constructor is an anomaly in this repo. Also it is ugly to have the type parameter hard coded in the function name.
The problem the constructor is trying to solve is that we don't like casts that don't obviously loose data. We have a solution for that already in `internals::ToU64`. This trait cannot be used in const contexts though so we do introduce a single cast in this patch.
