rextendr (version 0.4.0)

use_extendr: Set up a package for use with Rust extendr code

Description

Create the scaffolding needed to add Rust extendr code to an R package. use_extendr() adds a small Rust library with a single Rust function that returns the string "Hello world!". It also adds wrapper code so this Rust function can be called from R with hello_world().

Usage

use_extendr(
  path = ".",
  crate_name = NULL,
  lib_name = NULL,
  quiet = FALSE,
  overwrite = NULL,
  edition = c("2021", "2018")
)

Value

A logical value (invisible) indicating whether any package files were generated or not.

Arguments

path

File path to the package for which to generate wrapper code.

crate_name

String that is used as the name of the Rust crate. If NULL, sanitized R package name is used instead.

lib_name

String that is used as the name of the Rust library. If NULL, sanitized R package name is used instead.

quiet

Logical indicating whether any progress messages should be generated or not.

overwrite

Logical scalar or NULL indicating whether the files in the path should be overwritten. If NULL (default), the function will ask the user whether each file should be overwritten in an interactive session or do nothing in a non-interactive session. If FALSE and each file already exists, the function will do nothing. If TRUE, all files will be overwritten.

edition

String indicating which Rust edition is used; Default "2021".
