Project the prepared CDict window extent and destination match-state fields
through an explicit ABI state so Rust owns the post-reset attachment
operation. Preserve the original empty-dictionary and already-advanced
window branches, including window-limit clearing and loaded-dictionary
referential updates, while keeping private C pointer arithmetic and layout
ownership in the C adapter.
Test Plan:
- CARGO_BUILD_JOBS=1 cargo test --lib zstd_compress_dictionary::tests::reset_cctx_by_attaching_cdict -- --nocapture
- CARGO_BUILD_JOBS=1 cargo clippy --all-targets -- -D warnings
- CARGO_BUILD_JOBS=1 cargo test
- CARGO_BUILD_JOBS=1 make -j1
- CARGO_BUILD_JOBS=1 make -j1 -C tests test-zstream ZSTREAM_TESTTIME=-T2s
- CARGO_BUILD_JOBS=1 make -j1 -C tests test-fuzzer FUZZERTEST=-T3s FUZZER_FLAGS=--no-big-tests
All commands were run serially with a 40 GiB virtual-memory cap.
