%description
Provides a framework for creating high-performance 'R' packages powered by
the 'Rust' programming language using the 'extendr' Rust crate.  It offers
'usethis'-like functions to scaffold and develop 'Rust' powered 'R'
packages, including utilities for publishing to CRAN, managing
dependencies, configuring development environments, and rendering 'Rust'
code in 'knitr' documents. Additionally, it provides functions to compile
and evaluate 'Rust' code directly from 'R' for interactive development.
