Adapter trait for std::fmt::Debug.

Provides string representations for debugging and inspection in R. Automatically implemented for any type that implements Debug.

Methods

• debug_str() - Returns compact debug string (:? format)
• debug_str_pretty() - Returns pretty-printed debug string (:#? format)

Example

#[derive(Debug, ExternalPtr)]
struct Config { name: String, value: i32 }

#[miniextendr]
impl miniextendr_api::adapter_traits::RDebug for Config {}

Required Methods

fn debug_str(&self) -> String

Get a compact debug string representation.

fn debug_str_pretty(&self) -> String

Get a pretty-printed debug string with indentation.

Provided Methods

#[doc(hidden)]

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

where Self: Sized + RDebug,

Method shim for RDebug::debug_str.

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

#[doc(hidden)]

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

where Self: Sized + RDebug,

Method shim for RDebug::debug_str_pretty.

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 dyn compatible.

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