Version currency for the virtual-keyboard keymap in pf-inject's wlroots path
(`inject/linux/wlr.rs`), the crate's only consumer.
Additive on the Rust side: one new wrapper, `Keymap::key_get_mods_for_level`,
and the `extern` declaration behind it. Nothing we call changed shape -- we use
`Context::new`, `Keymap::new_from_names`, `get_as_string`, `State::new`,
`Keycode::new`, `KeyDirection` and the `serialize_mods`/`serialize_layout` pair,
all untouched. The feature set is unchanged too: `default = ["wayland"]` in both
releases, so `x11` -- the feature that would pull `as-raw-xcb-connection` -- stays
off and this links only `libxkbcommon`, exactly as before.
The one thing worth writing down is the new symbol's floor. On .25's
libxkbcommon 1.13.1 it reads
`xkb_keymap_key_get_mods_for_level@@V_1.0.0`, so the declaration wants
libxkbcommon >= 1.0.0 (2020) if it is ever referenced. Nothing in the workspace
calls the wrapper, so no relocation for it reaches our binaries -- and every ship
target clears 1.0 by years regardless (Ubuntu 22.04 is 1.4, Debian 12 is 1.5,
Debian 13 is 1.7). pf-inject's test binary, which unlike the rlib actually links,
builds and runs clean.
Two internal fixes come along, both in constructors we do not use:
`new_from_string` passes the Rust string's pointer + length to
`xkb_keymap_new_from_buffer` instead of round-tripping through a `CString`
(whose `unwrap()` panicked on an interior NUL), and `new_from_fd` passes the
full mapped `size` rather than `size - 1`.
Verified on .25 (Ubuntu 26.04, `CARGO_BUILD_JOBS=2`), all rc=0:
cargo build -p pf-inject --locked
cargo clippy -p pf-inject --locked -- -D warnings
cargo clippy -p pf-inject --all-targets --locked -- -D warnings
cargo test -p pf-inject --locked 127 passed, 0 failed, 8 ignored
+ motion_contract: 7 passed, 0 failed
cargo check -p punktfunk-host --locked
cargo clippy -p punktfunk-host --locked -- -D warnings
cargo fmt --all --check
Clippy is run BOTH ways because host CI lints without `--all-targets`.
`cargo tree -i ring` stays empty.
