Struct konst::alloc_type::VEC_NEW

pub struct VEC_NEW<T>(_);

This is supported on crate feature alloc only.

An empty Vec<T>. Usable to construct a [Vec<T>; N].

As of Rust 1.51.0, [Vec::new(); LEN] is not valid, because Vec<T> isn’t copy, but [CONST; LEN] does work, like in the example below.

Example

use konst::alloc_type::VEC_NEW;

use std::borrow::Cow;

const VECS: [Vec<u64>; 3] = [VEC_NEW::<u64>::V; 3];

let mut vecs = VECS;

vecs[0].extend_from_slice(&[3]);
vecs[1].extend_from_slice(&[5, 8]);
vecs[2].extend_from_slice(&[13, 21, 34]);

assert_eq!(vecs, [&[3][..], &[5, 8], &[13, 21, 34]]);

Implementations
