Trait AltListData

pub trait AltListData: AltrepLen {
    // Required method
    fn elt(&self, i: usize) -> SEXP;
}

Expand description

Trait for types that can back an ALTLIST vector.

List elements are arbitrary SEXPs, so this trait works with raw SEXP.

Required Methods§

Get the list element at index i.

Returns a SEXP (any R object).

This trait is dyn compatible.

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