Previously we've used `try_into().expect()` because const generics were
unavailable. Then they became available but we didn't realize we could
already convert a bunch of code to not use panicking conversions. But we
can (and could for a while).
This adds an extension trait for arrays to provide basic non-panicking
operations returning arrays, so they can be composed with other
functions accepting arrays without any conversions. It also refactors a
bunch of code to use the non-panicking constructs but it's certainly not
all of it. That could be done later. This just aims at removing the
ugliest offenders and demonstrate the usefulness of this approach.
Aside from this, to avoid a bunch of duplicated work, this refactors
BIP32 key parsing to use a common method where xpub and xpriv are
encoded the same. Not doing this already led to a mistake where xpriv
implemented some additional checks that were missing in xpub. Thus this
change also indirectly fixes that bug.
The extension traits are temporary just while we try to stabalize
`primitives`, they are not intended to be implemented by downstream.
Seal the extension traits so that downstream crates cannot implement
them.
Fix: #3231
We had an initial go at this but we didn't do the `Hash` trait method.
In order to do so we need to hack the serde code a fair bit, note the
public visitor types.
In preparation to move script types to `primitives` we replace impl
block with extension traits by replacing the temporary modules with
`define_extension_trait`.
The macro was trying to "parse" the parameters of functions defined in
extension trait. This was not needed and it was causing problems around
the `self` parameter. In this commit we change the macro to just pass
the parameters through.
`foo(&self)` is syntax sugar for `foo(self: &Self)`.
The `define_extension_trait` is currently large, ugly, and not that
expressive. If we use `self: &Self` then the macro is greatly
simplified.
De-sugar only, no logic changes.
We would like to move the `Script` type to `primitives` without moving
any key stuff, including pubkey hashes. We may later, before releasing
`primitives`, move the `WPubkeyHash` at which time this patch can be
reverted or re-implemented on `ScriptBuf`.
The `ScriptBuf::p2wpkh_script_code` function does not take `self` as a
parameter but it does return `Self` - this can trivially be made into a
standalone function.
Make `ScriptBuf::p2wpkh_script_code` a standalone function.
Now that the `define_extension_trait` can handle function parameters on
individual lines revert the manual formatting that was introduced in
PR #2955.
Refactor only, no logic changes.
Done in preparation for moving the script types to `primitives`.
The script types have a bunch of functionality to support scriptPubkeys,
and scriptPubkeys are an address thing.
Create a module under `address` and in it create a bunch of extension
traits to hold all scriptPubkey functionality.
Includes adding an ugly-as-hell macro to create the traits.
