Module runtime 

Source
Expand description

Rust-native R C API runtime.

These functions deref raw SEXP pointers from C code — this is inherently unsafe but required for C API compatibility. We suppress the clippy lint at module level since every function in this module works with raw pointers.

Implements the R C API functions (Rf_allocVector, Rf_protect, etc.) as extern "C" Rust functions that are compiled into the miniR binary. Package .so files resolve these symbols at load time.

setjmp/longjmp-based functions (Rf_error, _minir_call_protected) are in csrc/native_trampoline.c (compiled via build.rs) because longjmp is not safely callable from Rust.

Structs§

AllocNode 🔒
Linked list node for tracking allocations.
ExtPtrData 🔒
InterpreterCallbacks
Callback function pointers set by the Rust interpreter before each .Call.
RCallMethodDef
Rcomplex
RuntimeState 🔒
Thread-local allocation state for the current .Call invocation. This is in the binary (shared by all packages), not per-.so.
SendPtr
Wrapper for raw pointers that is Send (safe because we only access from single-threaded contexts).
