From 1e07212370806f3ea4ff7a6f66e5716b60ab1f77 Mon Sep 17 00:00:00 2001 From: Robin Krahl Date: Tue, 14 Jan 2020 19:21:26 +0100 Subject: Bump nitrokey dependency to version 0.5.1 This change updates the version of the nitrokey crate that we use to 0.5.1. As part of that, it replaces occurrences of Storage::get_status with Storage::get_storage_status as the method has been renamed.
