In extendr/rextendr: Call Rust Code from R using the 'extendr' Crate

rextendr (development version)

• use_extendr() sets the DESCRIPTION's SystemRequirements field according to CRAN policy to Cargo (Rust's package manager), rustc (#329)
• Introduces new functions use_cran_defaults() and vendor_pkgs() to ease the publication of extendr-powered packages on CRAN. See the new article CRAN compliant extendr packages on how to use these (#320).
• rust_sitrep() now better communicates the status of the Rust toolchain and available targets. It also guides the user through necessary installation steps to fix Rust setup (#318).
• use_extendr() and document() now set the SystemRequirements field of the DESCRIPTION file to Cargo (rustc package manager) if the field is empty (#298).
• use_extendr() gets a new ability to overwrite existing rextendr templates (#292).
• use_extendr() sets publish = false in the [package] section of the Cargo.toml (#297).
• use_extendr() correctly handles calls with path not equal to "." (current folder), or when there is no active {usethis} project (#323).
• Fixes an issue in pre-defined set of known features: added either (#338)
• create_extendr_package() allows user to create project directory using RStudio's Project Command. (#321)
• Support RTOOLS44 (#347)
• Removed use_try_from as an option in rust_function, and added use_rng (#354)

rextend 0.3.1

• Update package templates to work with Rust >= 1.70 (#285)

rextendr 0.3.0

• Ilia Kosenkov is now the official maintainer.

• Josiah Parry is now a contributor.

• Support Rtools43 (#231).

• rextendr has migrated to the use of cli for raising errors and warnings.

• Developer note: new helper function local_quiet_cli() introduced in R/utils.R to simplify silencing cli output.

New features

• A new function rust_sitrep() that prints out a short report on the currently installed Rust toolchain (#274).

• A new function write_license_note() to generate LICENSE.note file from Cargo.toml (#271).

• extendr_fn_options parameter of rust_source() controls what type of options are emitted to #[extendr()] attribute (#252).

• use_dev_extendr flag makes rust_source() family of functions compile code using development version of extendr. Development configuration is stored as an option named rextendr.extendr_dev_deps (#251).

• features parameter of rust_source() now correctly enables features in extendr-api and references required crates. features not available in release version of extendr raises a warning (#249).

• A <pkg_name>-win.def file containing DLL exports is created by rextendr::use_extendr(). It is used during linking phase on Windows and solves the problem of compiling very large projects, such as polars (#212)

• Support extendr macro with options (#128).

• rust_source() got features argument to specify Cargo features to activate (#140).

• rextendr::document() now sets the envvars that devtools::document() sets, e.g. NOT_CRAN (#135).
