Module nonempty_collections::array

Extends non-zero length arrays with conversion methods to non-empty collections.

Since fixed-size arrays are by definition already not empty, they aren’t given a special wrapper type like crate::NEVec. Instead, we enable them to be easily iterated over in a compatible way:

use nonempty_collections::*;

let a: [u32; 4] = [1, 2, 3, 4];
let v: NEVec<_> = a.into_nonempty_iter().map(|n| n + 1).collect();
assert_eq!(nev![2, 3, 4, 5], v);

See NonEmptyArrayExt for more conversions.

Caveats

These extensions are only provided for arrays up to size 32.

Structs

• ArrayNonEmptyIterator
  Non-empty iterator for arrays with length > 0.

Traits
