rextendr: Build 'Rust' Powered 'R' Packages

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.
