Trait InferBase 

pub trait InferBase {
    const BASE: RBase;

    // Required methods
    unsafe fn make_class(
        class_name: *const i8,
        pkg_name: *const i8,
    ) -> R_altrep_class_t;
    unsafe fn install_methods(cls: R_altrep_class_t);
}

Trait for inferring the R base type from a data type’s implemented traits.

This is automatically implemented via blanket impls for types that implement one of the Alt*Data traits. It allows the #[miniextendr] macro to infer the base type without requiring an explicit base = \"...\" attribute.

Required Associated Constants

const BASE: RBase

The inferred R base type.

Required Methods

unsafe fn make_class( class_name: *const i8, pkg_name: *const i8, ) -> R_altrep_class_t

Create the ALTREP class handle.

Safety

Must be called during R initialization.

unsafe fn install_methods(cls: R_altrep_class_t)

Install ALTREP methods on the class.

Safety

Must be called during R initialization with a valid class handle.

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.
