Trait RClone 

pub trait RClone {
    // Required method
    fn r_clone(&self) -> Self;

    // Provided method
    #[doc(hidden)]
    unsafe extern "C" fn __RClone_r_clone_shim(
        data: *mut c_void,
        argc: i32,
        argv: *const SEXP,
    ) -> SEXP
       where Self: Sized + RClone + IntoR { ... }
}

Adapter trait for std::clone::Clone.

Provides explicit deep copying for R. This is useful when R users need to create independent copies of Rust objects (which normally use reference semantics via ExternalPtr).

Methods

• r_clone() (clone() in R) - Create a deep copy of this value

Example

#[derive(Clone, ExternalPtr)]
struct Buffer { data: Vec<u8> }

#[miniextendr]
impl miniextendr_api::adapter_traits::RClone for Buffer {}

In R:

buf1 <- Buffer$new(...)
buf2 <- buf1$RClone$clone()  # Independent copy

Required Methods

fn r_clone(&self) -> Self

Create a deep copy of this value.

Provided Methods

#[doc(hidden)]

unsafe extern "C" fn __RClone_r_clone_shim( data: *mut c_void, argc: i32, argv: *const SEXP, ) -> SEXP

where Self: Sized + RClone + IntoR,

Method shim for RClone::r_clone.

Converts SEXP arguments, calls the method, and returns SEXP result. Both Rust panics and R longjmps are caught via with_r_unwind_protect.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
