Trait std::array::FixedSizeArray

pub unsafe trait FixedSizeArray<T> {
    fn as_slice(&self) -> &[T];
    fn as_mut_slice(&mut self) -> &mut [T];
}
🔬 This is a nightly-only experimental API. (fixed_size_array #27778)

Utility trait implemented only on arrays of fixed size

This trait can be used to implement other traits on fixed-size arrays without causing much metadata bloat.

The trait is marked unsafe in order to restrict implementors to fixed-size arrays. User of this trait can assume that implementors have the exact layout in memory of a fixed size array (for example, for unsafe initialization).

Note that the traits AsRef and AsMut provide similar methods for types that may not be fixed-size arrays. Implementors should prefer those traits instead.
