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.
