check_mdrb() returns a boolean indicating whether a suitable version of the metabodecon Rust backend mdrb is currently installed.

check_mdrb_deps() returns a list with information about the installation status of mdrb system dependencies.

Usage

check_mdrb(stop_on_fail = FALSE)

check_mdrb_deps(verbose = FALSE)

Arguments

stop_on_fail: If TRUE, an error is thrown if the check fails, providing instructions on how to install or upgrade mdrb.
verbose: If TRUE, additional information is printed during the check process.

Value

check_mdrb() returns TRUE if a suitable version of mdrb is installed, else FALSE.

check_mdrb_deps() returns a data.frame as follows:

            check           passed  comment
    r       R >= 4.2        TRUE    Current: R 4.4.2
    rtools  Rtools exist    TRUE    Tested with: pkgbuild::has_build_tools()
    cargo   cargo >= 1.80   TRUE    Current: cargo 1.84.1 (66221abde 2024-11-19)
    rustc   rustc >= 1.80   TRUE    Current: rustc 1.84.1 (e71f9a9a9 2025-01-27)
