Trait AltList 

pub trait AltList: AltVec {
    const HAS_SET_ELT: bool = false;

    // Required method
    fn elt(x: SEXP, i: R_xlen_t) -> SEXP;

    // Provided method
    fn set_elt(_x: SEXP, _i: R_xlen_t, _v: SEXP) { ... }
}

List vector methods.

REQUIRED: elt must be implemented (no default). R will error with “must provide an Elt method” if you don’t provide it.

Provided Associated Constants

const HAS_SET_ELT: bool = false

Set to true to register set_elt.

Required Methods

fn elt(x: SEXP, i: R_xlen_t) -> SEXP

Get list element at index. Returns any SEXP. This is REQUIRED for ALTLIST - there is no default.

Provided Methods

fn set_elt(_x: SEXP, _i: R_xlen_t, _v: SEXP)

Set element (for mutable lists).

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.
