[PATCH libgpiod v3 00/10] bindings: rust: prepare v1.0.0 release

[Bartosz Golaszewski]

The libgpiod rust bindings interface has stayed quite stable over the
last months so it's time for it to stop being a v0.x release and become
officially carved in stone. Bump dependencies to the most recent versions
available, fix some issues and then bump versions of the crates ahead of
the official release.

Changes in v3:
- Bump the minimum required rustc version to v1.78 after all to satisfy
  more recent versions of bindgen and system-deps
- Link to v2: https://lore.kernel.org/r/20250815-rust-1-0-0-release-v2-0-b1794cb4b9be@linaro.org

Changes in v2:
- drop the patch bumping the minimum required rust version
- loosen the requirements on the dependency versions: specify only the
  major number for stable crates and the major.minor for unstable ones
- Link to v1: https://lore.kernel.org/r/20250812-rust-1-0-0-release-v1-0-372d698f23e8@linaro.org

[PATCH libgpiod v3 01/10] bindings: rust: make Buffer::read_edge_events() lifetimes more explicit

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

Fix an issue pointed out by newer rustc version in the Buffer struct.
struct Events stores a reference to the buffer so tie the lifetime of the
latter to it explicitly.

[PATCH libgpiod v3 02/10] bindings: rust: add missing unsafe block ahead of rust version bump

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

Rust edition 2024 changed the semantics of the unsafe keyword used as
function modifier[1]. Unsafe operations inside unsafe functions must
still be wrapped in an unsafe {} block. Update the code in case we want
to bump the rust version or check it with clippy --edition 2024.

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

recent version. We now need to call CargoCallbacks::new() when boxing
the ParseCallbacks trait.

[PATCH libgpiod v3 05/10] bindings: rust: update errno dependency

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

Bump the errno dependency for gpiosim-sys and libgpiod crates to the
most recent version which is a minor update from the one we have now.
However: let cargo select it automatically by not specifying the bugfix
version. We need to be stricter than just selecting the major version
alone because crates with major versions starting with 0 can introduce
breaking changes in minor releases. No code changes required.
