About rextendr
rextendr put Rust-backed R packages in the browser, then tore itself down for a 1.0.0 rebuild
rextendr is the R-side toolchain for extendr, scaffolding and compiling R packages with Rust internals. The package is mid-teardown: the 0.4-final tag in October 2025 warns that main may not work as expected and directs users to install from that tag, and April 2026's release is titled as one more developer release before 1.0.0. Meanwhile the CRAN-facing 0.4.x line did the substantive work.
