Builds the real upstream pybind11 C++20 extension plus the bundled rust_indexing binary from source (no sdist upstream, so checked out at the release tag). No CUDA/GPU, pure Rust deps (zstd/crossbeam/ filebuffer/clap/glob), Apache-2.0.

infini-gram2.6.0Builds a pybind11 C++20 n-gram index engine plus a bundled
cargo build --releaseindexing binary, both from source. Upstream publishes no riscv64 wheel (and no sdist at all, so the build checks out the release tag).Mirrors upstream's own
pkg/pyproject.tomlcibuildwheel config (rustup install before-build,cp3*-manylinux*).Differs from upstream
CIBW_BUILDto one interpreter per matrix job - upstream's own config builds every interpreter in one invocation.Testing
License: OK. Apache-2.0; no third-party binaries vendored - the
rust_indexingbinary and the C++ extension are both compiled from the checked-out source, and the dependency crates (zstd, crossbeam, filebuffer, clap, glob) are all permissively licensed pure Rust.Verified no CUDA/GPU code and no byte-order/pointer-size assumptions that would be riscv64-specific: the C++ engine uses plain POSIX
mmap/size_t/fixed-width ints throughout.
