Struct REngine 

pub struct REngine;

Handle to an initialized R runtime.

This is a marker type indicating R has been initialized for this process. R cleanup (via Rf_endEmbeddedR) is intentionally NOT called because it performs non-reentrant operations that can crash if called during Drop or concurrent with other cleanup. The OS reclaims all resources on process exit.

Implementations

impl REngine

pub fn build() -> REngineBuilder

Create a new builder for configuring R initialization.

pub unsafe fn process_events(&self)

Process pending R events.

Call this periodically to allow R to handle events, especially when running a long computation.

Safety

Must be called from the thread that initialized R.

pub unsafe fn check_interrupt(&self)

Check for user interrupts (Ctrl+C).

Safety

Must be called from the thread that initialized R.

Trait Implementations

impl Drop for REngine

fn drop(&mut self)

Implements drop such that std::mem::forget leaks REngine rather than dropping it, when Drop is absent.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
