Trait Flatten 

pub unsafe trait Flatten<T, N, M>: GenericSequence<GenericArray<T, N>, Length = M>
where
    N: ArrayLength + Mul<M>,
    Prod<N, M>: ArrayLength,
{
    type Output: GenericSequence<T, Length = Prod<N, M>>;

    // Required method
    fn flatten(self) -> Self::Output;
}

Defines a GenericSequence of GenericArrays which can be flattened into a single GenericArray, at zero cost.

Safety

While the flatten method is marked safe, care must be taken when implementing it. However, the given trait bounds should be sufficient to ensure safety.

Required Associated Types

type Output: GenericSequence<T, Length = Prod<N, M>>

Flattened sequence type

Required Methods

fn flatten(self) -> Self::Output

Flattens the sequence into a single GenericArray.

Example

assert_eq!(
    arr![arr![1, 2], arr![3, 4], arr![5, 6]].flatten(),
    arr![1, 2, 3, 4, 5, 6]
);

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
