CHANGELOG

The change log for the Rust socketcan library.

Version 3.4.0 (2024-12-26)

Re-implemented CAN raw sockets using socket2
Added a 'CanId' type with more flexibility than embedded_can::Id
Moved from UD utility functions and types from frame module to id
Added a CAN FD example, echo_fd
Split out CanAddr and related code into a new addr module.
New CanRawFrame encapsulatea either type of libc, raw, CAN frame (Classic or FD)
Raw frame reads for CanSocket and CanFdSocket.
Implemented Read and Write traits for CanSocket
InterfaceCanParams now has all items as Option<>. Can be used to get or set multiple options.
#58 Add new API to enumerate available SocketCAN interfaces
#60 Make CanState public
#61 CanFdSocket read_frame crash fix
#64 Make termination u16 and add set_termination
#65 Dump parsing also optionally trims off CR at the line end
#66 1CanInterface1: add 1set_can_params1 method to set multiple parameters
#67 Improved tokio async implementation
#68 remove unnecessary qualifications
#73 Update some dependencies
- itertools to v0.13, nix to v0.29, bitflags to v2.6, mio to v1
#74 CanFDFrames with ExtendedID are not correctly parsed by socketcan::dump::Reader
#75 Fix DLC and add padding for CANFD frames
#76 Add CanCtrlModes::has_mode(mode: CanCtrlMode)
#80 Friendly non-Linux compilation error
- Remove unused byte_conv dependency

#32 Added a number of netlink commands to modify the CAN interface parameters. including: setting the bitrate and (for FD) setting the data bitrate, setting control modes, manually restarting the interface, and setting the automatic restart delay time.
- PR #50 Add set_bitrate method
PR #45 Dump handles extended IDs
PR #44 Fix clippy warnings
PR #43 Implement AsPtr for CanAnyFrame

Made CanAddr pulic and added functions to help interact with low-level sockaddr types. Sockets can now be opened with an address.
Can create an Error directly from a CanErrorFrame or std::io::ErrorKind.
#46 Applications can create error frames:
- CanErrorFrame::new() now works.
- CanErrorFrame::new_error() is similar but more intuitive using a raw ID word.
- From<CanError> for CanErrorFrame to create an error frame from a CanError.
Added Frame::from_raw_id() and Frame::remote_from_raw_id()
Bumped MSRV to 1.65.0

Extensive rework of the crate to cleanup, refactor, and modernize the library and add some new features like CAN FD support.

Moved to Rust Edition 2021 w/ MSRV 1.64
Refactored frames into differnt types: Data, Remote, Error (and now FD), that can be managed through enumeraed wraper types CanFrame and/or CanFdFrame
Pushed some implementation upsream to the libc and nix crates, and/or adapted upstream types.
- CAN 2.0 frames based on libc::can_frame
- CAN FD frames based on libc::canfd_frame
#33 Netlink extensions
- Creating and deleting interfaces
- Setting MTU (to/from FD)
#21 New CI using GitHub Actions
#20 Composite PR with some modernization
- Pulls in #13, and updates to the latest neli v0.6
- Updates nix dependency to latest v0.23
- Moves to Rust 2018 w/ MSRV 1.54
- Errors conform to std::error::Error
#16 Add CAN FD support
#24 Embedded HAL Traits
- Plus some source refactoring into more coherent modules
