Function malachite_base::strings::exhaustive::exhaustive_fixed_length_strings

pub fn exhaustive_fixed_length_strings(
    len: u64,
) -> StringsFromCharVecs<ExhaustiveFixedLengthVecs1Input<ExhaustiveChars>> 

Generates all [String]s of a given length.

The output length is $1112064^n$, where $n$ is len.

If len is 0, the output consists of one empty [String].
