From 4fb865af37093d9b0ee039d8ae48fb2a820f3760 Mon Sep 17 00:00:00 2001 From: Robin Krahl Date: Tue, 28 Jan 2020 17:38:47 +0100 Subject: Represent serial numbers using SerialNumber struct In a previous commit, we changed the serial number representation from a string to an integer. This made it easier to compare serial numbers, but also introduced new problems: - Serial numbers should be formatted consistently, for example as "{:#010x}". It is hard to ensure this for an integer value. - The format of the serial number may be subject to change. Users should not rely too much on the u32 representation. Therefore we introduce a new SerialNumber struct that represents a serial number. Currently it only stores a u32 value. The following traits and functions can be used to access its value: - FromStr for string parsing - ToString/Display for string formatting - as_u32 to access the underlying integer value --- tests/device.rs | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'tests') diff --git a/tests/device.rs b/tests/device.rs index 2989941..1669d9d 100644 --- a/tests/device.rs +++ b/tests/device.rs @@ -10,7 +10,7 @@ use std::{thread, time}; use nitrokey::{ Authenticate, CommandError, CommunicationError, Config, ConfigureOtp, Device, DeviceInfo, Error, GenerateOtp, GetPasswordSafe, LibraryError, OperationStatus, OtpMode, OtpSlotData, - Storage, VolumeMode, DEFAULT_ADMIN_PIN, DEFAULT_USER_PIN, + SerialNumber, Storage, VolumeMode, DEFAULT_ADMIN_PIN, DEFAULT_USER_PIN, }; use nitrokey_test::test as test_device; @@ -47,7 +47,7 @@ fn list_devices(_device: DeviceWrapper) { nitrokey::Model::Pro => { assert!(device.serial_number.is_some()); let serial_number = device.serial_number.unwrap(); - assert!(serial_number != 0); + assert!(serial_number != SerialNumber::empty()); } nitrokey::Model::Storage => { assert_eq!(None, device.serial_number); @@ -163,7 +163,7 @@ fn get_status(device: DeviceWrapper) { #[test_device] fn get_serial_number(device: DeviceWrapper) { let serial_number = unwrap_ok!(device.get_serial_number()); - assert!(serial_number != 0); + assert!(serial_number != SerialNumber::empty()); } #[test_device] -- cgit v1.2.3
