Formats the value using the given formatter.

impl<T: Default, const R: usize, const C: usize> Default for ArrayStorage<T, R, C>

where [[T; R]; C]: Default,

fn default() -> Self

Returns the “default value” for a type.

impl<T: PartialEq, const R: usize, const C: usize> PartialEq for ArrayStorage<T, R, C>

fn eq(&self, other: &ArrayStorage<T, R, C>) -> bool

This method tests for self and other values to be equal, and is used by ==.
