Struct varlen::array_init::CloneFrom
source · [−]pub struct CloneFrom<'a, T>(pub &'a [T]);Expand description
Fills an array by cloning from a source array. Source and destination must have identical length.
Examples
use varlen::prelude::*;
let src = ["hello".to_string(), "world".to_string()];
let arr: [String; 2] = new_array(CloneFrom(&src));
assert_eq!(src, arr);Panics
Panics if the source and destination have different lengths.
