These methods are either newtype casts that should compile to no-ops or
directly calling into some other function with at most some pointer
adjustments. As such making them `#[inline]` is definitely benefitial.
There are also methods that check length and then call some other
function. These are also worth inlining since the length could be known
at compile time and the check could be eliminated.
We have several trait implementations for `Script` and `ScriptBuf` in a
common module so that it's easy to verify that they are same but `Deref`
and `DerefMut` should *not* be implemented for `Script` so having them
in the common module is not helpful. This moves them to the appropriate
`Owned` module.
The newtype sanity rules (a name I came up with):
* Newtypes should have at most one constructor that directly references
the inner field.
* Newtypes should have at most three accessor methods that directly
reference the ineer field: one for owned access, the second for
borrowed and the third for mutably borrowed.
* All other methods should use the methods above to perform operations
on the newtype and not directly access the fields.
This commit makes `Script` and `ScriptBuf` obey these except for
`reserve` and `reserve_exact` since we don't have `as_mut_vec` method.
As a side effect it also adds `const` to `ScriptBuf::from_bytes`.
Rust macros, while at times useful, are a maintenance nightmare. And
we have been bitten by calling macros from other crates multiple times
in the past.
In a push to just use less macros remove the usage of the
`impl_from_infallible` macro in all the leaf crates and just write the
code.
Woops, this should have been done before v0.101.0 was released.
Move the `ScriptHash` and `WScriptHash` types to `primitives`.
Requires moving constants and error types as well. We re-export the
errors because they are in the `mod.rs` file so they should appear in
both `primitives::script::FooError` and `bitcoin::script::FooError`.
Enable lint `clippy::return_self_not_must_use` and add attribute
`must_use` as required.
Also run the linter with `clippy::must_use_candidate` enabled and
manually check every warning site.
While we are at it change the current `must_use` usages to have no
message. We can always add a message later if needed.
In functions that act like constructors there is a mixture of the usage
of `creates` and `constructs`.
Replace all occurrences of `creates` with `constructs` in the first line
of docs of constructor like functions.

Pull request description:
Use `to_vec` and deprecate `to_bytes`, the opposite of what we did in #2585.
For functions that return a `Vec` by first allocating use function name `to_vec`. This explicitly excludes:
- Functions that return an array (`CompressedPublicKey::to_bytes`)
- Functions that consume self and return a `Vec` without allocating (`ScriptBuf::into_bytes`)
See #3025 for discussion and consensus.

We want our code to be easy to read and our APIs discoverable, for those
of us who read source files the layout matters.
Put the constructors and getters at the top of the impl block.
Code move only, no logic changes.
Deprecate the `Script::to_bytes` function in favour of `to_vec` as we
are doing elsewhere.
Note that `ScriptBuf` has `into_bytes` because it does not copy.
Potentially this should be deprecated in favour of `into_vec`?
Note that in regards to the `to_` prefix this naming as valid according
to convention because the `Script` type is borrowed and `to_vec` copies
the underlying bytes.
In the `script` module remove the wildcards and re-export stuff from
`self` explicitly in both `primitives` and `bitcoin`.
Internal change only, everything is re-exported.
Currently we feature gate code within the `impl_to_hex_from_lower_hex`
macro on "alloc" but `bitcoin` does not have the "alloc" feature so
this code is never built in. This can be seen by the lack of a
`to_hex` function on `LeafVersion`.
Remove the feature gate from the macro and put it on the individual
call sites as needed.
