All `Wallet` constructors are modified to require a change descriptor, where previously it was optional. Additionally we enforce uniqueness of the change descriptor to avoid ambiguity when deriving scripts and ensure the wallet will always have two distinct keystores. Notable changes * Add error DescriptorError::ExternalAndInternalAreTheSame * Remove error CreateTxError::ChangePolicyDescriptor * No longer rely on `map_keychain`

//! HWI Signer

//! This crate contains HWISigner, an implementation of a [`TransactionSigner`] to be
|
|
//! used with hardware wallets.

//! ```no_run
