Route match-state invalidation through a Rust leaf. C still computes the
private window pointer difference and passes the opaque dictionary-state
pointer, while Rust preserves the window-limit, next-index, dictionary,
optimal-parser, and dictionary-match-state reset order. Add a focused test
for all invalidated fields and use the concrete C pointer type at the ABI
boundary to avoid strict-aliasing warnings.
Test Plan:
- cargo fmt --manifest-path rust/Cargo.toml -- --check
- ulimit -v 41943040 && CARGO_BUILD_JOBS=1 cargo clippy --manifest-path rust/Cargo.toml --all-targets -- -D warnings
- ulimit -v 41943040 && CARGO_BUILD_JOBS=1 cargo test --manifest-path rust/Cargo.toml zstd_compress::tests::invalidate_match_state -- --nocapture
- ulimit -v 41943040 && make -j1
- ulimit -v 41943040 && make -j1 -C tests test-fuzzer FUZZERTEST=-T3s FUZZER_FLAGS=--no-big-tests
