Struct extendr_api::wrapper::Pairlist

pub struct Pairlist<NV> {
    pub names_and_values: NV,
}

Wrapper for creating pair list (LISTSXP) objects.

use extendr_api::prelude::*;
test! {
    let names_and_values = (0..100).map(|i| (format!("n{}", i), i));
    let expr = r!(Pairlist{names_and_values});
    assert_eq!(expr.len(), 100);
}

    NV: IntoIterator + 'a,
    NV::Item: SymPair, 

fn from(val: Pairlist<NV>) -> Self

Convert a wrapper to a LISTSXP object.

use extendr_api::prelude::*;
test! {
    let names_and_values = (0..100).map(|i| (format!("n{}", i), i));

}

impl<NV: PartialEq> PartialEq<Pairlist<NV>> for Pairlist<NV>

fn eq(&self, other: &Pairlist<NV>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Pairlist<NV>) -> bool

This method tests for !=.
