This function generates wrapper code corresponding to the extendr module for an R package. This is useful in package development, where we generally want appropriate R code wrapping the Rust functions implemented via extendr. In most development settings, you will not want to call this function directly, but instead call rextendr::document().

## Usage

register_extendr(path = ".", quiet = FALSE, force = FALSE, compile = NA)

## Arguments

path

Path from which package root is looked up.

quiet

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

force

Logical indicating whether to force re-generating R/extendr-wrappers.R even when it doesn't seem to need updated. (By default, generation is skipped when it's newer than the DLL).

compile

Logical indicating whether to recompile DLLs:

TRUE

always recompiles

NA

recompiles if needed (i.e., any source files or manifest file are newer than the DLL)

FALSE

never recompiles

## Value

(Invisibly) Path to the file containing generated wrappers.

## Details

The function register_extendr() compiles the package Rust code if required, and then the wrapper code is retrieved from the compiled Rust code and saved into R/extendr-wrappers.R. Afterwards, you will have to re-document and then re-install the package for the wrapper functions to take effect.
