From 9240ce015ca91316c99845de220e4813eb443d37 Mon Sep 17 00:00:00 2001 From: Leonardo Lima Date: Fri, 16 May 2025 19:36:25 -0300 Subject: [PATCH 1/5] feat(signer): add new `SignerWrapper` for `KeyMap` - adds a new `SignerWrapper` for `KeyMap` as a test utility, with new methods: `get_wallet_signer` and `get_wallet_signer_single`. - adds an implementation of `GetKey` trait for `SignerWrapper`, in order to retrieve the private key for software signers, and successfully use `Psbt::sign` method. - the new methods added are necessary, in order to update the existing tests and examples to use `Psbt::sign` instead of `Wallet::sign`, as it further allows the signing APIs and related types to be fully removed. --- wallet/src/test_utils.rs | 163 ++++++++++++++++++++++++++++++++++++++- 1 file changed, 160 insertions(+), 3 deletions(-) diff --git a/wallet/src/test_utils.rs b/wallet/src/test_utils.rs index 11fd13b1..befb9e96 100644 --- a/wallet/src/test_utils.rs +++ b/wallet/src/test_utils.rs @@ -3,14 +3,171 @@ use alloc::string::ToString;
