This introduces a new interface named NetworkParams and updates the
functions that currently take a pointer to a chaincfg.Params struct to
accept the interface instead.
This removes the tight coupling between the two packages at the API
boundary and allows callers to easily provide custom values without
having to create and register and entire chaincfg network as previous
required.
Finally, the README.md is updated accordingly.
This removes the Address method from the ExtendedKey struct since
ultimately there will be multiple address types and therefore it no
longer makes sense to return an address which probably isn't the one the
caller actually needs. Instead, the caller can make use of the ECPubKey
method to obtain the public key and create the desired address from
there.
It also removes the related tests, updates the example to show the
address conversion process for a standard pay-to-pubkey-hash address,
and updates the README.md and doc.go files accordingly.
This updates the README.md in hdkeychain to account for changes made in
Decred, correct the NewMaster godoc example link, and format the
examples so the description is on the line after the link for
consistency with other packages in the code base.
This change moves the hdkeychain package outside of the dcrutil
directory into its own top-level package. This change is being made
since hdkeychain only depends on dcrutil's address code, and if the
rpctest integration tests are ever moved outside of the dcrd repo,
hdkeychain will no longer be required to remain in dcrd to avoid a
cyclic dependency.
