Trait RClone 

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

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

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

Example

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

#[miniextendr]
impl RClone for Buffer {}

In R:

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

Required Methods

fn clone(&self) -> Self

Create a deep copy of this value.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
