[PATCH V4 0/8] libgpiod: Add Rust bindings

by Viresh Kumar

Hello, Here is another version of rust bindings for libgpiod v2.0, based of the next/libgpiod-2.0. Pushed here: https://github.com/vireshk/libgpiod master 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.
