Pull request description:
This is a straight up move of the whole type because there are only three methods, a getter, a setter, and `is_signalling_soft_fork`.
If we use an extension trait for `is_signalling_soft_fork` then we have to make the two private associated consts public which is in my opinion worse.
Patch 1 is preparation, use getter/setter, patch 2 does the move.

Pull request description:
Following up on https://github.com/rust-bitcoin/rust-bitcoin/issues/630#issuecomment-2392050517.
I amended the docstring on `InputWeightPrediction::weight()` to clarify that it only returns the signature weight. I'm not sure what the rationale was for only returning partial input weight, and if there are any arguments against something like `InputWeightPrediction::total_weight()` which returns `self.weight() + Weight::from_non_witness_data_size(32 + 4 + 4)` (and maybe deprecate `weight()` eventually to prevent misuse).

This is a straight up move of the whole type because there are only
three methods, a getter, a setter, and `is_signalling_soft_fork`.
If we use an extension trait for `is_signalling_soft_fork` then we
have to make the two private associated consts public which is in my
opinion worse.
In preparation for moving the `block::Version` type over to `primitives`
stop using the private constructor and inner field. Use the public
getter/setter instead (`to_consensus`and `from_consensus` respectively).
We would like to move the `Witness` to `primitives` however in the
`Encodable` implementation we are currently accessing the private
`content` field.
Instead of accessing `content` we can iterate over the witness elements
and write each individually, this has the same result but does a bunch
of additional calls to `Write::write_all` (via `emit_slice`).
This patch effects performance negatively but makes no changes to the
encoding.
The `Witness::push_slice` function is called by `Witness::push` after
calling `as_ref`, hence is equivalent for all types that implement
`AsRef<[u8]>`. Also, `push_slice` is a private method on `Witness`.
In preparation for moving `Witness` over to `primitives` stop using
`push_slice` in favour of `push`.
Internal change only.
In preparation for moving the `Witness` oven to `primitives` use the
`len` function instead of accessing the `witness_elements` field.
No logic change, `Witness::len()` returns `witness_elements`.

Move the `OutPoint` type and associated code over to `primitives`. Take
the opportunity to re-order the code so the file reads like a story,
things are implemented below where they are called.
Our `define_extension_trait` macro cannot handle examples in rustdocs,
since these docs are on the deprecated `OutPoint::is_null` function just
remove them.
In preparation for moving the `OutPoint` to `primitives` add an
additional impl block that holds everthing that will stay here in
`bitcoin`.
Internal change only.
Rust convention is to not use `test_` prefix on unit tests. Also this
unit test is testing that the `ExactSizedIterator` trait is implemented
and working.
Re-name unit test to `exact_sized_iterator`.
In preparation for moving unit tests to `primitives` give the serde
tests some love by doing:
- Split them up to do one thing only
- Round trip arbitrary witness
- Use better names
Make an effort to clean up the encoding unit test, by doing:
- Remove element accessor assertions (tested already above)
- Add roundtrip encoding assertion
33edaf935d fix: check overflow for push_int with push_int_unchecked (Chris Hyunhum Cho)
876146154b refactor: use push_lock_time instead of push_int (Chris Hyunhum Cho)
Pull request description:
Fix the issue https://github.com/rust-bitcoin/rust-bitcoin/issues/1530. In the discussion of https://github.com/rust-bitcoin/rust-bitcoin/issues/1530, the suggested solution is to implement `ScriptInt` type to embrace the various type of integer(`i32, u32, i64, u64, i128, u128, isize, usize...`) to support both script number and locktime number.
However, as `push_locktime` and `push_sequence` implemented, there’s no need to support `u32` of lock time for `push_int` anymore. Therefore, I’ve just changed the type of parameter to `i32`, and only check if it’s `i32::MIN`(which overflows 4 bytes sign-magnitude integer).
~I also added push_uint method to use internally for `push_locktime` and `push_sequence`, which have a dependency on `push_int` method.~
UPDATE: also add `push_int_unchecked` for those who want to push the integer out of range(and helper for `push_locktime` and `push_sequence`, which has the same functionality of former `push_int`.

The current unit test is incorrect, the indices field of a witness with
a single element starts at 1 because 0 is encode as a single
byte (compact encoded integer).
Fix the debug test and add a test that pushes an empty slice.
Recently we removed the `all_zeros` function from `OutPoint` in favour
of a more meaningfully named associated const. We can do the same for
`BlockHash`, the all zeros has is used for the previous blockhash of the
genesis block, add a const named as such.
In test code where we use the `all_zeros` function, just use the more
explicit form `from_byte_array([0; 32])`.
Currently we provide `Default` implementations for a couple of types in
the `transaction` module, the values returned are meaningless and it
seems these impls were added to make writing test code easier. In
hindsight this was the wrong thing to do.
Break the API and remove the `Default` implementations for `OutPoint`
and `TxIn`.
Add an associated const `TxIn::EMPTY_COINBASE` that is, as the name
suggests, an empty transaction input with the prevout set to all
zeros as for the coinbase transaction.
At some stage we named the compact encoding `VarInt` (which makes sense
because the compact size encoding is a variable length integer encoding).
However it turns out the term "varint" is used in Core for a different
encoding so this may lead to confusion.
While we fix this naming thing observe also that the `VarInt` type is
unnecessarily complicated, all we need to be able to do is encode and
decode integers in compact form as specified by Core. We can do this
simply by extending our `WriteExt` and `ReadExt` traits.
Add `emit_compact_size` and `read_compact_size` to emit and read compact
endcodings respectively.
Includes addition of `internals::compact_size::encoded_size_const`.
Patch originally written by Steven, Tobin cherry-picked and did a bunch
of impovements after the varint vs compact_size thing (#1016).

We would like to add a `emit_varint` function, however doing so requires
that we can get access to the length of a slice when we are encoding it
so we can use `emit_slice` to implement `emit_varint`. It would be
easier to do so if `emit_slice` returned the length of the slice.
In preparation for adding `emit_varint` (and removing the `VarInt` type)
return the encoded length of a slice from `WriteExt::emit_slice`.

The `Builder` is staying in `bitcoin` while the `ScriptBuf` is moving to
`primitives`, so we cannot access the inner field of `ScriptBuf`.
Use the new `as_byte_vec` hack to mutate the inner `ScriptBuf` field.
In preparation for moving the `ScriptBuf` type to `primitives` stop
accessing the inner field when encoding/decoding, use `as_script`
and `from_bytes` instead.
In preparation for moving the `Script` type to `primitives` stop
accessing the inner field before doing slice operations, use `as_bytes`
to first get at the slice.
The `Script::fmt_asm` function is a legacy from days yore before
`Display` printed asm. We no longer need it.
Deprecate `Script::fmt_asm` and use the private `bytes_to_asm_fmt` or
`Display` impls.
Use the `define_extension_trait` macro to define two extension traits
for the two txid types. Each trait holds the deprecated `all_zeros`
function. There are no users of this trait in the code base.
Recently we deprecated the `all_zeros` functions on `Wtxid` and
`Txid` but for some reason our usage of them is not triggering a lint
warning.
Note please that this changes logic slightly, for example by using an
array of `0xFF` bytes instead of all zeros. Done in an effort to make it
even more obvious that the value is a dummy value and not mix it up with
the all zeros being used for coinbase thing.
In #3308 we added associated consts to the `Txid`, `Wtxid`, and
`OutPoint` types. During review and afterwards we realised the docs
could do with improving. Since we now want to move the types we should
do this first.

The `UintError` type (returned by `read_uint_iter`) is not that useful
because one variant is unreachable. Re-write the function by doing:n
- Re-write the function to reduce the error cases returned.
- Re-name it to `read_push_data_len`
- Move it to `internals`
- Use `PushDataLenLen` enum instead of an int parameter
333c8ab297 Add additional docs to Witness (Tobin C. Harding)
Pull request description:
The `Witness` struct is non-trivial, in particular it is not immediately obvious where and when the compact size encode value for each witness element is stored.
Make an effort to improve the docs on `Witness` in relation to the compact size encoded length of each witness element.

Currently we have `all_zeros` functions and `null` functions but we can
do better.
Add associated consts and improve the names to better describe what
these dummy zero hashes are used for.
Deprecate related functions.
We would like to move the witness module to `primitives` but there is
a bunch of usage of `VarInt`.
Introduce a module that does the encoding and decoding instead, this
code is internal so put it in `internals`.
Note we add an unused public `MAX_ENCODABLE_SIZE` variable that is
commented with an issue link. Done like this because its quite
important that we see to it and it makes it clear that we are not and
we know about it.

1fde868f51 Separate Version impl blocks (Tobin C. Harding)
Pull request description:
As per title, in tiny small chunks, move the `transaction::Version` over to `primitives`. Only the type, its associated consts, and its `Display` impl are moved. The two methods are left in an extension trait.
Was originally attempted in #3253

We would like to move the `Transaction` type to `primitives`, as a step
towards this move the `transaction::Version` and its trait imps (just
`Display`) over there.
In preparation for adding an extension trait; separate the
`transaction::Version` impl blocks into stuff that will stay here and
stuff that will go to `primitives`.
Refactor only, no logic changes.
30bb93c676 Implement impl_to_hex_from_lower_hex macro for types that implement fmt::LowerHex (Shing Him Ng)
Pull request description:
Created a macro that implements `to_hex` for types that currently have `core::fmt::LowerHex` and called it on types that have `core::fmt::LowerHex` implemented. I put the macro in the `internals` crate since there are types across the whole project that can potentially use this.
Resolves#2869

345d3daa72 fix: deprecate wrong and unused max script num (ChrisCho-H)
Pull request description:
~~Script number can be up to 2^39 - 1 to encode locktime.~~
~~If it's only for the integer operation besides locktime, it must be 2^31 - 1, not 2^31.~~
I agree with apoelstra opinion to deprecate this value.

The two `TxOut` fields are public and there are no construtors or
getters to move, only the associated const `NULL`.
Add a tmp module around the big impl block so we can trick the formatter
into indenting before we add the extension trait.
