Struct RandomStringBuilder 

pub struct RandomStringBuilder { /* private fields */ }

A random String builder, providig fined-grained control over what a random String should contain.

If no charsets are supplied, the build() step will produce a None value.

Examples

Random phone number

use random_str::random::{RandomStringBuilder, CharBuilder};

let digits: Option<String> = RandomStringBuilder::new()
    .with_length(10)
    .with_numbers()
    .build();
let random_phone_number = format!("+52 {}", digits.unwrap());
println!("Random phone number: {}", random_phone_number);

Random password

use random_str::random::{RandomStringBuilder, CharBuilder};

let random_password: Option<String> = RandomStringBuilder::new()
    .with_length(32)  // Optional, 16 as default
    .with_lowercase()
    .with_uppercase()
    .with_numbers()
    .with_symbols()
   .build();
println!("Random password: {}", random_password.unwrap());
