Struct core_extensions::phantom::AndPhantomCov
source · [−]#[repr(transparent)]pub struct AndPhantomCov<T>(pub PhantomData<fn() -> T>, pub T);Available on crate feature
phantom only.Expand description
A pair of PhantomData<fn() -> T> and T.
useful for infering the type of the value from a PhantomData.
Example
use core_extensions::{AndPhantomCov, AsPhantomData};
use std::marker::PhantomData;
let foo = [0, 1, 2];
let mut bar = AndPhantomCov(foo.as_phantom_covariant(), Default::default()).1;
bar[0] = 3;
bar[1] = 5;
bar[2] = 8;
assert_eq!(bar[..], [3, 5, 8]);
