Making an array of structs works only for some array sizes [duplicate]

I made a simple struct and implemented Default for it:

#[derive(Clone, Copy)]
struct LifeCell {
    state: usize
}

impl Default for LifeCell {
    fn default() -> LifeCell {
        LifeCell {
            state: 0
        }
    }
}

I'm trying to create an array of such structs:

const TOTAL_CELLS: usize = 20;
let mut new_field: [[LifeCell; TOTAL_CELLS]; TOTAL_CELLS] = Default::default();

This compiles okay until I set TOTAL_CELLS to 35. Then it doesn't compile with an error:

error[E0277]: the trait bound `[[LifeCell; 35]; 35]: std::default::Default` is not satisfied
  --> src/main.rs:14:65

   = help: the following implementations were found:
             <&'a [T] as std::default::Default>
             <&'a mut [T] as std::default::Default>
             <[T; 32] as std::default::Default>
             <[T; 31] as std::default::Default>
           and 31 others
   = note: required by `std::default::Default::default`

I know the reason for it - at the moment, the Default trait is implemented only for array sizes up to 32. But what should I do if I need an array of structs that is bigger than that?

I'm using Rust 1.18.0.
