embedded-hal-mock

This release contains a big change: embedded-hal-mock now supports both embedded-hal 0.x and 1.x! The two variants are accessible through embedded_hal_mock::eh0::* and embedded_hal_mock::eh1::*. If there are any issues, leave feedback in the GitHub issue tracker.

Additionally, tests now fail if you forgot to call .done(). This should reduce the chance of accidentally writing a broken test.

This release contains commits by 12 different people, thanks a lot for the contributions!

Migrating to 0.10.0

• Update your imports: Change use embedded_hal_mock::* to use embedded_hal_mock::eh0::*
• Rename all .expect(...) calls on mocks to .update_expectations(...)
• Rename all eh0::delay::MockNoop usages to eh0::delay::NoopDelay
• Run your tests to ensure that you don't have any missing .done() calls in your code
• Look through the rest of the changes below and check if they might affect your code

Added

• Support for both embedded-hal 0.x and 1.x in the same crate (#75)
• Print a warning to stderr and fail test if a mock is dropped without having calling .done() on it, or if .done() is called twice (#59, #61)
• Implement mock for eh1::pwm::SetDutyCycle

Fixed

• Generic mock: Fix a bug that caused the call to .done() to fail if .next() was called on the mock after all expectations have already been consumed (#58)
• Fix assertion error message for SPI transfer and transfer_in_place (#90)

Changed

• Renamed .expect(...) method to .update_expectations(...) to avoid confusion with the expect method in Option and Result (#63)
• When updating expectations on a mock by calling .expect(...) / .update_expectations(...) on it, assert that previous expectations have been consumed (#63)
• Rename delay::MockNoop to delay::NoopDelay.
• Changed the eh1 SPI implementation to be generic over word size
• Updated nb dependency from 0.1 to 1.1 (#107)
• Bump minimal supported Rust version (MSRV) to 1.63 (or 1.75 if you use embedded-hal 1.0)
• The minimal supported Rust version (MSRV) is specified in the Cargo.toml to offer clearer error messages to consumers with outdated Rust versions

Added

• Implement WriteIter and WriteIterRead for i2c mock (#44)
• Implement PwmPin for pin mock (#52)
• Add mock for timers using embedded-time with nanosecond precision (#40)

Changed

• Bump minimal supported Rust version (MSRV) to 1.60
• Switch to Rust 2021 edition (#55)
• Switch from CircleCI to GitHub Actions (#50)

Added

• Add one-shot ADC mock (#38)

Added

• Implement std::Error trait for MockError (#31)
• serial: Implement error expectations (#32)

Added

• i2c: Implement error expectations (#29)

Fixed

• Fix link to digital pin docs (#28)

Added

• The serial transaction API now has two new constructor methods: read_many and write_many.

Changed

• The serial transaction API changed: The Transaction::write function now expects a single word, not a collection of words. To add a transaction for many writes, use Transaction::write_many instead.

Fixed

• Make the serial mock actually cloneable

Added

• Add serial device mock (#21)
• Add InputPin and OutputPin mocks (#18)

Changed

• MockError::Io now wraps an io::ErrorKind instance instead of io::Error.

Added

• SPI: Add support for non-blocking FullDuplex mode (#14)

Changed

• Require Rust 1.31+

Added

• Add StdSleep delay implementation based on std::thread::sleep (#8)
• Add new() methods to MockNoop and StdSleep

Fixed

• Fix error messages for unfulfilled I²C expectations (#12)

Changed

• I²C mock has a new transaction based API, matching the SPI mock (#4)

Added

• SPI mock implementation (#2)
• Set up CI (#3)

Changed

• Restructure crate:
  • I2cMock is now at i2c::Mock
  • DelayMockNoop is now at delay::MockNoop
• Move all docs into crate docs (so it can be tested)

Changed

• Upgrade to embedded-hal 0.2.
