Trait RegisterAltrep 

pub trait RegisterAltrep {
    // Required method
    fn get_or_init_class() -> R_altrep_class_t;
}

Registration trait: implemented per type by the macro on struct items.

The get_or_init_class method returns the ALTREP class handle, initializing it on first call and returning the cached handle on subsequent calls.

This trait combines class creation and method installation into a single get_or_init_class call that caches the result.

Required Methods

fn get_or_init_class() -> R_altrep_class_t

Get the ALTREP class handle, initializing it if this is the first call.

The implementation should:

1. Create the class handle via R_make_alt* (or via InferBase::make_class)
2. Install methods via install_* functions from altrep_bridge
3. Cache the result in a static OnceLock

Dyn Compatibility

This trait is not dyn compatible.

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