Struct core_extensions::phantom::AndPhantom
source · [−]#[repr(transparent)]pub struct AndPhantom<T>(pub PhantomData<T>, pub T);
Available on crate feature
phantom
only.Expand description
A pair of PhantomData<T>
and T
.
useful for infering the type of the value from a PhantomData
.
Example
use core_extensions::{AndPhantom, AsPhantomData};
use std::marker::PhantomData;
let foo = vec![0, 1, 2];
let mut bar = AndPhantom(foo.as_phantom(), Default::default()).1;
bar.push(3);
bar.push(4);
assert_eq!(bar[..], [3, 4]);
Tuple Fields
0: PhantomData<T>
1: T
