Struct yapg::PasswordGenerator

pub struct PasswordGenerator { /* fields omitted */ }

Encapsulates RNG and set of characters. See crate documentation for more.

Implementations

impl PasswordGenerator

pub fn new(charset: Vec<char>, length: usize) -> Self

Creates the PasswordGenerator to yield passwords using either PasswordGenerator::generate or PasswordGenerator::generate_n charset will not be deduplicated, so that you could (but should not!) increase the the probability density of the chars in the generated passwords.

pub fn length(self, length: usize) -> Self

Changes the length of the generated passwords, consumes and returns itself.

pub fn generate(&mut self) -> String

Generates one password, with characters randomly chosen from the charset.

pub fn generate_n(&mut self, n: usize) -> Vec<String>

Generates a vector of passwords with length n, calling PasswordGenerator::generate internally. Cannot return an iterator, because that iterator would need to hold a mutable reference to the generator.

pub fn combinations(&self) -> f64

Number of all possible combinations arising from charset and length.

pub fn entropy(&self) -> usize

Entropy of the generated passwords in bits.
