Hello,
Here is another version of the rust bindings, based of the master branch.
Pushed here:
https://github.com/vireshk/libgpiod v8
V7->V8: - Several updates to cargo.toml files, like license, version, etc. - Removed Sync support for chip and gpiosim. - Implemented, in a separate patch, iterator support for Events. - Fixed missing SAFETY comments. - Fixed build for 32 bit systems. - Use errno::Errno. - Removed Clone derive for many structures, that store raw pointers. - line setting helpers return the object back, so another helper can be called directly on them. Also made all helpers public and used the same in tests and example for single configurations. - Enums for gpiosim constants. - New examples to demonstrate parallelism and event handling. - Separated out HTE tests and marked as #[ignore] now. - Updated commit subjects. - Other minor changes.
V6->V7: - Don't let buffer read new events if the earlier events are still referenced. - BufferIntenal is gone now, to make the above work. - Update example and tests too for the same.
V5->V6: - Updates according to the new line-settings interface. - New file, line_settings.rs. - Renamed 'enum Setting' as 'SettingVal' to avoid conflicting names, as we also have 'struct Settings' now. - Support for HTE clock type. - Implement 'Eq' for public structure/enums (reported by build). - Remove 'SettingKindMap' and 'SettingMap' as they aren't required anymore. - Updated tests based on new interface.
V4->V5: - Arrange as workspace with crates for libgpiod-sys, libgpiod, gpiosim. - Use static libgpiod and libgpiosim libraries instead of rebuilding again. - Arrange in modules instead of flattened approach. - New enums like Setting and SettingKind and new types based on them SettingMap and SettingKindMap. - New property independent helpers for line_config, like set_prop_default(). - Improved tests/examples, new example for gpiowatch. - Add pre-built bindings for gpiosim too. - Many other changes.
V3->V4: - Rebased on top of new changes, and made changes accordingly. - Added rust integration tests with gpiosim. - Found a kernel bug with tests, sent a patch for that to LKML.
V2->V3: - Remove naming redundancy, users just need to do this now use libgpiod:{Chip, Direction, LineConfig} now (Bartosz); - Fix lifetime issues between event-buffer and edge-event modules, the event buffer is released after the last edge-event reference is dropped (Bartosz). - Allow edge-event to be copied, and freed later (Bartosz). - Add two separate rust crates, sys and wrapper (Gerard). - Null-terminate the strings passed to libgpiod (Wedson). - Drop unnecessary checks to validate string returned from chip:name/label/path. - Fix SAFETY comments (Wedson). - Drop unnecessary clone() instances (Bartosz).
V1->V2: - Added examples (I tested everything except gpiomon.rs, didn't have right hardware/mock device to test). - Build rust bindings as part of Make, update documentation.
Thanks.
