pub fn exhaustive_fixed_length_strings(
    len: u64
) -> StringsFromCharVecs<ExhaustiveFixedLengthVecs1Input<ExhaustiveChars>>ⓘNotable traits for StringsFromCharVecs<I>impl<I: Iterator<Item = Vec<char>>> Iterator for StringsFromCharVecs<I>    type Item = String;

Expand description

Generates all Strings 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.

Examples

extern crate itertools;
