Struct GetManyMutError

Source
pub struct GetManyMutError<const N: usize> { /* private fields */ }
🔬This is a nightly-only experimental API. (get_many_mut #104642)
Expand description

The error type returned by get_many_mut<N>.

It indicates one of two possible errors:

  • An index is out-of-bounds.
  • The same index appeared multiple times in the array.

§Examples

#![feature(get_many_mut)]

let v = &mut [1, 2, 3];
assert!(v.get_many_mut([0, 999]).is_err());
assert!(v.get_many_mut([1, 1]).is_err());
