Trait Implementations

impl<P: Clone, NV: Clone> Clone for Env<P, NV>

fn clone(&self) -> Env<P, NV>

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<P: Debug, NV: Debug> Debug for Env<P, NV>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, P, NV> From<Env<P, NV>> for Robj where
    P: Into<Robj>,
    NV: IntoIterator + 'a,
    NV::Item: SymPair, 

fn from(val: Env<P, NV>) -> Self

Convert a wrapper to an R environment object.

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

impl<P: PartialEq, NV: PartialEq> PartialEq<Env<P, NV>> for Env<P, NV>

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

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

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

This method tests for !=.
