Crate libR_sys

Expand description

A low-level libR binding library which is kept deliberately minimal.

In particular, it has no external dependencies other that libR installed on the target.

§Synopsis

The libR-sys crate is a low level bindgen wrapper for the R programming language. The intention is to allow one or more extension mechanisms to be implemented for rust.

Effort to make the extension libraries platform-independent can be concentrated here.

§Examples

use libR_sys::{Rf_initialize_R, R_CStackLimit, setup_Rmainloop};
use std::os::raw;

unsafe {
  std::env::set_var("R_HOME", "/usr/lib/R");
  let arg0 = "R\0".as_ptr() as *mut raw::c_char;
  Rf_initialize_R(1, [arg0].as_mut_ptr());
  R_CStackLimit = usize::max_value();
  setup_Rmainloop();
}

§Conditional compilation depending on R installation

The libR-sys crate provides these environmental variables that you can use in build.rs:

DEP_R_R_VERSION_MAJOR: The major part of the R version (e.g. 4 in version 4.1.0)
DEP_R_R_VERSION_MINOR: The minor part of the R version (e.g. 1 in version 4.1.0)
DEP_R_R_VERSION_PATCH: The patch part of the R version (e.g. 0 in version 4.1.0)
DEP_R_R_VERSION_DEVEL: true if the R is a development version, otherwise false
DEP_R_R_VERSION_STRING: The full version string (e.g. R version 4.1.0 (2021-05-18))
DEP_R_R_HOME: The R home directory

§Example `build.rs`

use std::env;

fn main() {
    // Set R_HOME envvar, and refer to it on compile time by env!("R_HOME")
    let r_home = env::var("DEP_R_R_HOME").unwrap();
    println!("cargo:rustc-env=R_HOME={}", r_home);

    // Enable cfg setting to conditionally compile a code using a feature
    // available only on newer versions of R
    let major = env::var("DEP_R_R_VERSION_MAJOR").unwrap();
    let minor = env::var("DEP_R_R_VERSION_MINOR").unwrap();
    if &*major >= "4" && &*minor >= "1" {
        println!("cargo:rustc-cfg=use_a_feature");
    }
}

Structs§

GESystemDesc
R_CMethodDef: These are very similar to those in Rdynpriv.h, but we maintain them separately to give us more freedom to do some computations on the internal versions that are derived from these definitions.
R_CallMethodDef
R_GE_gcontext: A structure containing graphical parameters
R_allocator
R_altrep_class_t
R_hashtab_type: try to allow some type checking
R_inpstream_st
R_outpstream_st
Rcomplex: R 4.3 redefined Rcomplex to a union for compatibility with Fortran. But the old definition is compatible both the union version and the struct version. See: https://github.com/extendr/extendr/issues/524
Rf_RegisteredNativeSymbol
SEXPREC

_iobuf

Enums§

GEUnit: The graphics engine will only accept locations and dimensions in native device coordinates, but it provides the following functions for converting between a couple of simple alternative coordinate systems and device coordinates: DEVICE = native units of the device NDC = Normalised device coordinates INCHES = inches (!) CM = centimetres (!!)
GEevent
N01type: Different kinds of “N(0,1)” generators :
NativeSymbolType
ParseStatus: PARSE_NULL will not be returned by R_ParseVector
RNGtype
R_GE_lineend: Some line end/join constants
R_GE_linejoin
R_KeyName: These give the indices of some known keys
R_MouseEvent: These are the three possible mouse events
R_pstream_format_t
Rboolean
SEXPTYPE: —— enum_SEXPTYPE —–
Sampletype: Different ways to generate discrete uniform samples
_bindgen_ty_1: ALTREP sorting support
cetype_t: cetype_t is an identifier reseved by POSIX, but it is well established as public. Could remap by a #define though
nchar_type: ../main/character.c :

PROTECT_INDEX: We sometimes need to coerce a protected value and place the new coerced value under protection. For these cases PROTECT_WITH_INDEX saves an index of the protection location that can be used to replace the protected value using REPROTECT.
R_CFinalizer_t: Finalization interface
R_ExternalMethodDef
R_FortranMethodDef: These are very similar to those in Rdynpriv.h, but we maintain them separately to give us more freedom to do some computations on the internal versions that are derived from these definitions.
